Expert Solution
Step 1: Average and instantaneous rates of the reaction
- The average rate of a reaction is calculated as the change in the concentration of the reactant over a course of time for which the whole reaction is carried out.
- The instantaneous rate of a reaction is the change in concentration of the reactant at an instant of time considered.
