Chapter 20, Problem 112SAE

Interpretation Introduction

Interpretation:

Order of the reaction from the given reactant concentration versus time plot nature should be determined.

Concept introduction:

A rate law expression defines the relationship between the rate of reaction and the concentration of reactants.

Consider a reaction,

$a\text{A}+b\text{B}\to \text{Products}$

The rate law for the above equation can be defined as,

$r=k{\left[\text{A}\right]}^a{\left[\text{B}\right]}^b$

As the reaction proceeds, the concentration of reactants decreases and the concentration of products increases.

The amount of time which a substance takes to lose its half of the initial concentration is defined as half-life.
