You will get an additional universal credit payment called the disabled child addition for each dependent child you have on DLA or PIP.

The diffusion rate depends on several factors: the concentration gradient (the increase or decrease in concentration from one point to another); the amount of surface area available for diffusion; and the distance the gas particles must travel.

Many retirement planners suggest the typical 401(k) portfolio generates an average annual return of 5% to 8% based on market conditions. But your 401(k) return depends on different factors like your contributions, investment selection and fees.

Interest Rates Right now, the prime rate sits at 5.5%, so your 401(k) loan rate will come out between 6.5% and 7.5%. The interest rate is the same regardless of your credit score, which is one reason why so many people find 401(k) loans tempting.

The rate of decomposition is dependent on litter quality and environmental conditions. Soil temperature and moisture content are very important factors affecting decomposition rates. At favorable moisture conditions, increasing temperature results in an exponential increase in decomposition rates (Q10 of approx 2).

The temperature and concentration are factors that affect the magnitude. An increase in temperature increases the rate constant and hence the rate. An increase in concentration increases the rate but not the rate constant. the rate of a reaction depends on the rate constant and concentration.

Answer: Rate constant of a reaction depends on temperature. Generally rate constant increases with increase in temperature. The effect of temperature on the rate constant is expressed quantitatively by Arrhenius equation.

The specific rate constant (k) is the proportionality constant relating the rate of the reaction to the concentrations of reactants. The rate law and the specific rate constant for any chemical reaction must be determined experimentally. The value of the rate constant is temperature dependent.

A first-order reaction depends on the concentration of one reactant, and the rate law is: r=−dAdt=k[A] r = − dA dt = k [ A ] .

The temperature dependence of the reaction rate is contained in the rate constant (k), which is actually a constant only when the temperature remains constant. 13.13 Explain the meaning of each term within the Arrhenius equation: activation energy, frequency factor, and exponential factor.

Increasing the temperature of a reaction generally speeds up the process (increases the rate) because the rate constant increases according to the Arrhenius Equation. As T increases, the value of the exponential part of the equation becomes less negative thus increasing the value of k.

To calculate the compression spring rate of this spring, divide the load of 20 pounds by the distance traveled of 2”. The compression spring rate calculated will be of 10 pounds of force per inch. k = L ÷ T. k = 20 ÷ 2. k = 10 lbf/in.

What is the difference between average rate and constant rate? Average rate is the rate in which something can be done over a specific time interval. Constant rate assumes that the average rate is the same over any time interval.

With increase in temperature, the rate of the reaction and the rate constant increases.

As a generalization, the rate of the reaction (and the rate constant) becomes almost double for every ten degree rise in temperature.

This is also called temperature coefficient..

The mean growth rate constant (k) is the number of generations (n) per unit of time (t). k = n / t. In case of microorganisms it is usually expressed as generations per hour.

These are all included in the so-called rate constant (k)- which is only actually constant if all you are changing is the concentration of the reactants. If you change the temperature or the catalyst, for example, the rate constant changes. This is shown mathematically in the Arrhenius equation.

The majority of the rate constants were determined at a pressure of approximately 95 Torr. ... Given the close agreement between Howard's low pressure results and our higher pressure values, we conclude that the rate constant does not have a significant pressure dependence for temperatures between 200 and 300 K.

3 Answers. you can see that the rate constant increases for an increase in temperature (and as activation energy increases, the rate constant decreases. ... However, increasing the rate does not increase the rate constant. An increase in temperature increases the rate constant and hence the rate.

Gender and weight can affect basal metabolic rates. Basal metabolic rate is dependent upon age and genetics.

The rate equation shows the effect of changing the reactant concentrations on the rate of the reaction. All other factors affecting the rate—temperature and catalyst presence, for example—are included in the rate constant, which is only constant if the only change is in the concentration of the reactants.

For straight lines, the rate of change (slope) is constant (always the same). For such lines, the rate of change is constant.

Answer and Explanation: In mathematics, a constant rate of change is a rate of change that stays the same and does not change. That is, if quantity a has a constant rate of...

The rate of change is constant. 8. 10-3 Slope and Rate of Change When the rate of change is constant, the segments form a straight line. The constant rate of change of a line is its slope.

The rate law for a zero-order reaction is rate = k, where k is the rate constant. In the case of a zero-order reaction, the rate constant k will have units of concentration/time, such as M/s.

a) Calculate the dissolution rate constant (K = D/h) case 1 dM/dt =KS (Cs-Ct) = (0.000336 cm /sec)(5000 cm2)(15- 1.52 mg/ml) dM/dt = 22.646mg/sec case 2 dM/dt =KS (Cs) = (0.000302 cm /sec)(5000 cm2)(15mg/ml) dM/dt = 22.65 mg/sec case 1: not sink condition dM/dt =KS (Cs-Ct) dM/dt =0.76gm / 60 seconds = 0.01267 gm/sec X ...

Rate = k[A]y[B]z. The proportionality constant, k, is known as the rate constant and is specific for the reaction shown at a particular temperature. The rate constant changes with temperature, and its units depend on the sum of the concentration term exponents in the rate law.

Since the rate of radioactive decay is first order we can say: r = k[N]1, where r is a measurement of the rate of decay, k is the first order rate constant for the isotope, and N is the amount of radioisotope at the moment when the rate is measured.

The proportionality constant, k, is known as the rate constant and is specific for the reaction shown at a particular temperature. The rate constant changes with temperature, and its units depend on the sum of the concentration term exponents in the rate law.

A constant rate in math is the absence of acceleration. In general, a function with a constant rate is one with a second derivative of 0. If you were to plot the function on standard graph paper, it would be a straight line, as the change in y (or rate) would be constant.

What is the difference between rate of reaction and reaction rate constant? Rate of reaction is the change in concentration of a reactant or product per unit time. ... The rate constant is constant for a particular reaction at a particular temperature and does not depend upon the concentrations of the reactants.

20%There is a mandatory withholding of 20% of a 401(k) withdrawal to cover federal income tax, whether you will ultimately owe 20% of your income or not. Rolling over the portion of your 401(k) that you would like to withdraw into an IRA is a way to access the funds without being subject to that 20% mandatory withdrawal.

Interest Rates Like most loans (except maybe those from Mom and Dad), a 401(k) loan comes with interest. The rate is usually a point or two above the prime rate. Right now, the prime rate sits at 5.5%, so your 401(k) loan rate will come out between 6.5% and 7.5%.

Growth rate is constant not size dependent. There is inconclusive evidence of a correlation between growth rate and initial size. Instead of assuming that all crystals undergo random fluctuations in their growth rate, one assumes instead that each individual crystal has an inherent and constant growth rate.
