Chapter 14, Problem 128AP

Interpretation Introduction

Interpretation:

The order of reaction and time required to hydrolyze $95\%$ of sucrose are to be determined. Also, the reason that, ‘the rate law does not include $\left[{\text{H}}_2\text{O}\right]$ although it is a reactant in the reaction’, is to be explained.

Concept introduction:

The order of reaction is the number that relates the rate of a chemical reaction with the concentration of the reacting species in a chemical reaction.

The equation which relates the rate of a reaction to the concentration of reactants is the rate law. For the reaction as:

$a\text{A}+b\text{B}\to c\text{C}+d\text{D}$

The rate law is as follows:

$\text{rate}={\left[\text{A}\right]}^x{\left[\text{B}\right]}^y$

Rate constant for a reaction is the proportionality constantthatrelates the rate of reaction and the concentration of reactants in the reaction.
