Chapter 11, Problem 81E

Interpretation Introduction

Interpretation: The activation energy of decomposition reaction of hydrogen peroxideat $\text{20}°\text{C}$ with catalyst and at unknown temperature without catalyst is given. Based on these data,the temperature of uncatalyzed reaction for the decomposition of hydrogen peroxideis 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,

$k=A{e}^{\frac{-E_{\text{a}}}{RT}}$

To determine: The temperature of uncatalyzed reaction for the decomposition of hydrogen peroxide.
