Chapter 13, Problem 13.68QP

Interpretation Introduction

Interpretation:

Check whether the given reaction is first order or second order and the rate constant of the reaction has to be determined. 

Concept introduction:

Rate law: It is an equation that related to the rate of reaction to the concentrations or pressures of substrates (reactants).  It is also said to be as rate equation.

Rate equation for the general reaction $\text{A+B}\to \text{Product}$ is,

$Rate=\underset{\begin{array}{l}rate\\ constat\end{array}}{k}\left[A\right]\left[B\right]$

Order of a reaction:  The sum of exponents of the concentrations in the rate law for the reaction is said to be order of a reaction.

$\text{A}\to \text{Product}$

Rate law for this reaction is,

$rate=k{\left[A\right]}^1$ , and the order of this reaction is one.

A reaction with a constant half-life period generally follows first order kinetics.
