Rate of reaction or speed of reaction is change in concentration of reactant or product per unit time.It is decrease in conc. of reactant or increase in conc. of product.
For a hypothetical reaction aA + bB→ cC + dD
Average rate of reaction depends upon the change in concentration of reactants or products and the time taken for that change to occur
Instantaneous rate of reaction is defined as the average rate at the smallest time interval say dt ( i.e. when Δt approaches zero).

Answer:
The rate of reaction is defined as change of concentration of reactant and product per unit time divide by the corresponding coefficients given by balanced chemical reaction
Explanation:
average rate:- It is rate of reaction calculated for a long time interval
