Chapter 12, Problem 82AE

Interpretation Introduction

Interpretation: The change in activation energy of a reaction without catalyst at $\text{600}\text{K}$ and with catalyst is given. Also, the time of uncatalyzed reaction to occur is given. Based on these data, the time ofcatalyzed reaction is to be calculated.

Concept introduction: The substance that speeds up the rate of reaction without getting consumed itself in a chemical reaction is known as catalyst.

The relationship between the rate constant and temperature is given by the Arrhenius equation,

$\begin{array}{c}k=A{e}^{\frac{-E_{\text{a}}}{RT}}\\ \ln k=-\frac{E_{\text{a}}}{RT}+\ln A\end{array}$

To determine: The total time of catalyzed reaction.
