NEET Chemistry Rate of Reaction MCQ Question
For a second-order reaction, if the initial concentration of reactant X is doubled, how does the rate of the reaction change?
The rate increases by a factor of 4.
The rate increases by a factor of 2.
The rate remains unchanged.
The rate decreases by a factor of 2.
Correct Answer
Detailed Explanation
For a second-order reaction, the rate is proportional to the square of the concentration of the reactant. Doubling the concentration of X results in the rate increasing by a factor of 4.
