The rate constant for the formation of 'B' is — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

The overall rate constant is K_total = K_B + K_C = 1.5 × 10^-4 s^-1. The fraction of B formed is given by K_B / K_total = 0.10. Thus, K_B = 0.10 × 1.5 × 10^-4 = 1.5 × 10^-5 s^-1. Therefore, correct answer is C.
