Select the correct option based on statements below:
Assertion (A): Order and molecularity are the same.
Reason (R): Order is determined experimentally, and molecularity is the sum of the stoichiometric coefficient of the rate-determining the elementary step.
   
1. Both (A) and (R) are True and (R) is the correct explanation of (A).
2. Both (A) and (R) are True but (R) is not the correct explanation of (A).
3. (A) is True but (R) is False.
4. (A) is False but (R) is True.
HINT: Order and molecularity are not the same.
Explanation:
Order and molecularity may or may not be the same as the order of the reaction is the sum of the power of reactant which
can be determined experimentally. But molecularity is the sum of the stoichiometric coefficient of rate-determining the
elementary step.
