Chapter 14, Problem 14.93QP

Interpretation Introduction

Interpretation:

The rate law of the given reaction has to be determined.

Concept introduction:

Rate of a reaction: It represents the speed at which a chemical reaction runs. 

Rate of reaction depends on time, temperature, pressure and concentration of the reaction.

Rate law: It is an equation that relates the rate of a reaction to the concentrations or pressures of the substrates (reactants) in the reaction. 

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

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

Where,

x represents the order of the reactant A.

y represents the order of the reactant B.

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

The order of the considered generl reaction will be:

$\text{Order}\text{= }\text{x+y}$
