Chapter DY, Problem 3PQ

Interpretation Introduction

Interpretation:

The average rate of appearance of oxygen gas for the given reaction ${\text{2O}}_{\text{3(g)}}\stackrel{}{\to }{\text{3O}}_{\text{2(g)}}$ is $\text{1}{\text{.2×10}}^{\text{-3}}\text{atm}{\text{.s}}^{\text{-1}}$.  The average rate expresses in $\text{atm}{\text{.s}}^{\text{-1}}$, for the disappearance of ${\text{O}}_{\text{3}}$ has to be calculated.

Concept Introduction:

Rate of a reaction:

Speed at which the chemical reaction happens is known as rate of a reaction.  Slower the speed of the reaction, lower will be the rate.  Concentration, temperature, pressure, catalyst are the factors affecting rate of a reaction.

Rate law – it is a relationship between reaction rates and reactant concentrations

Average rate is the rate of a reaction calculated for a long time interval.
