NEET Chemistry Rate of Reaction Assertion Reason Question
Assertion (A): The rate of a chemical reaction increases with an increase in the concentration of reactants.
Reason (R): The number of collisions per unit time between reactant molecules increases with concentration.
Both (A) and (R) are true, and (R) is the correct explanation of (A).
Both (A) and (R) are true, but (R) is not the correct explanation of (A).
(A) is true, but (R) is false.
(A) is false, but (R) is true.
Correct Answer
Detailed Explanation
The rate of reaction depends on the concentration of reactants as more molecules result in more collisions per unit time, which is consistent with the collision theory described in the NCERT context.
