Question

Explain the difference between instantaneous rate of reaction and average rate of a reaction.

Answer 1

The instantaneous rate of reaction:
1. The rate of a reaction at a specified or particular point of time.
2. It occurs within a short span of time.
3. Instantaneous Rate of change:

Instantaneous Rate = $\frac{dx}{dt}=\frac{dP}{dT}$
The average rate of a reaction:
1. The rate of change of concentration of substances for a definite interval of time.
2. It occurs during a large span of time.
3. Average Rate of Change :

Average rate = $\frac{-\Delta A}{\Delta t}=\frac{A_2-A_1}{T_2-T_1}$.
