Chapter 14, Problem 43

Consider the tabulated data showing the initial rate of a reaction (A → products) at several different concentrations of A. What is the order of the reaction? Write a rate law for the reaction including the value of the rate constant, k.

<Identify the general form of the rate law for the reaction: \( \text{Rate} = k[A]^n \), where \( n \) is the order of the reaction.>
<Examine the tabulated data to determine how the initial rate changes with varying concentrations of \( A \).>
<Compare the rates and concentrations to find a pattern: if doubling \([A]\) doubles the rate, the reaction is first order; if doubling \([A]\) quadruples the rate, it is second order, etc.>
<Use the determined order \( n \) to write the rate law: \( \text{Rate} = k[A]^n \).>
<Calculate the rate constant \( k \) using one set of data from the table by substituting the values of rate and \([A]\) into the rate law equation.>
