A -K1-> P (1st order) and B -K2-> Q (2nd order). Same initial conc (1M), same time to reach 0.5M. — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

t_1/2 equal: 0.693/K1 = 1/K2 => K2 = 1.44*K1, so K2 > K1 (D correct). Initial rates: R_A0 = K1, R_B0 = K2. Since K2 > K1, initial rate of B greater (B correct).
