The rate constant of reaction is — Chemical Kinetics Chemistry Question

Question

The rate constant of reaction is

Answer: A

💡 Solution & Explanation

From the data, the half-life (t_1/2) is 100 min. For a first-order reaction, K = ln(2) / t_1/2 = 0.693 / 100 = 6.93 × 10^-3 min^-1. Therefore, correct answer is A.
