For the reaction: H2 + I2 ⇌(K1/K2) 2HI. The rate law expression is — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

The net rate of reaction is the rate of the forward reaction minus the rate of the backward reaction. Rate = 1/2 d[HI]/dt = Rate_forward - Rate_backward = K1[H2][I2] - K2[HI]^2. Therefore, correct answer is C.
