An agama lizard basks in … WebJun 9, 2015 · To find the initial rate of decay, simply differentiate the exponential equation and evaluate it at t = 0. The derivative is. so at t = 0, the slope is simply − k C ( 0) and the magnitude of the slope is k C ( 0). With k = 0.053 s − 1 and C ( 0) = 0.4 M, this yields 0 .021 M s − 1 as the initial rate magnitude.
Webthe reaction rate depends upon the concentration of each reactant. Two methods are commonly used in the experimental determination of the rate law: the method of initial rates and the graphical method. In this experiment, we shall use the method of initial rates to determine the rate law of a reaction. You should review the sections on ... WebThe initial rate of reaction under the same conditions, using 1.16 mol dm-3 of A and 1.53 mol dm-3 of B. First, let's find k. We can use what we are told about the orders of the reaction with respect to both A and B to write a rate equation. ... It decomposes in a first-order reaction. Calculate the rate constant, k, for this reaction. To ...
