To derive the integrated rate equation for a first-order reaction and determine the units of the first-order rate constant, we can follow these steps: 1. Understanding the Rate Law: For a first-order reaction, the rate of reaction (r) can be expressed as: r=−d(A)dt=k(A) where...
The Integrated Rate Law for a First-Order Reaction The rate constant for the first-order decomposition of cyclobutane, C4H8 at 500 °C is 9.2 × 10-3 s-1: C4H8→2C2H4C4H8→2C2H4 How long will it take for 80.0% of a sample of C4H8 to decompose? Solution We use the integrated form ...
The method of initial rates involves measuring the rates of reactions when the concentrations are changed. Answer and Explanation: The integrated rate law for a first-order reaction is used to determine the rate constant k. The formula for the ...
Consider a reaction for which the rate law is:rate=k[A]m[B]nrate=k[A]m[B]nIf the exponent m is 1, the reaction is first order with respect to A. If m is 2, the reaction is second order with respect to A. If n is 1, the reaction is first order in B. If n is 2, ...
