If rate constants for decomposition of N2O5, formation of NO2 and formation of O2 are K1, K2 and K3, — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

Rate of reaction = -1/2 d[N2O5]/dt = +1/4 d[NO2]/dt = +d[O2]/dt. Given the rate constants, this means 1/2 K1[N2O5] = 1/4 K2[N2O5] = K3[N2O5]. Thus, K1/2 = K2/4 = K3, which rearranges to 2K1 = K2 = 4K3. Therefore, correct answer is B.
