NEET Chemistry Rate of Reaction MCQ Question
Consider the following statements about the rate of reaction: 1) The half-life of a reaction for a first-order process is constant regardless of the initial concentration. 2) For a zero-order reaction, the half-life is directly proportional to the initial concentration. 3) The rate of a reaction can depend on the concentration of products as well as reactants. 4) The rate constant for a reaction changes with temperature. Which of the following combinations are correct?
1 and 4
2 and 3
1, 2, and 4
1, 2, 3, and 4
Correct Answer
Detailed Explanation
All statements are correct based on the NCERT context. The half-life for a first-order reaction is constant (statement 1), for a zero-order reaction it is dependent on the initial concentration (statement 2), the rate can depend on the concentration of products (statement 3), and the rate constant does change with temperature (statement 4).
