What is the rate constant of the reaction at the given temperature? — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

Using Data from Exp 1: K = Rate / ([OH][H2S]) = (1.4 × 10^-6) / (1.3 × 10^-8 × 2.1 × 10^-8) = 1.4 × 10^-6 / 2.73 × 10^-16 = 5.128 × 10^9 M^-1 s^-1. Therefore, correct answer is A.
