Give scientific reasons:
Zinc powder reacts faster than zinc granules when added to copper sulphate `(CuSO_4)` solution.

Text Solution

Verified by Experts

The rate of a chemical reaction depends upon the size of the reactant particles taking part in the reaction.
ii. Smaller the size of the reactant particles, faster is the reaction.
iii. The size of reactant particles is less in finely powdered zinc as compared to zinc granules. Hence, the reaction with copper sulphate takes place faster with finely powdered zinc than zinc granules.
