Chapter 14, Problem 14.73SP

Interpretation Introduction

Interpretation:

The half-life in minutes and the time required for the concentration of isonitrile to drop to $12.5\%$ of its initial value needs to be determined.

Concept introduction:

Time required for half the reaction to change is termed as a half-life period. It is denoted by the symbol $t_{1/2}$. The below formula is used to calculate $t_{1/2}$ of 1^st order reaction.

$t_{1/2}=\frac{0.6932}{k}$

Here, k represents rate constant.
