Chapter 15, Problem 80E

Interpretation Introduction

Interpretation:The rate constant for the first order decomposition of iodomethane at ${\text{325}}^{\text{o}}\text{ C}$ and the pressure of iodomethane after three half-lives needs to be determined.

Concept introduction: The relationship between temperature and rate constant is given by Arrhenius equation:

  $\begin{array}{l}{\text{k = Ae}}^{\text{-}\frac{{\text{E}}_{\text{a}}}{\text{RT}}}\\ \text{ln k = -}\frac{{\text{E}}_{\text{a}}}{\text{RT}}\text{ + ln A}\end{array}$

Where k is rate constant, A is frequency factor, E_a is activation energy, R is universal gas constant and T is temperature.
