The rate equation for an autocatalytic reaction A + R → R + R is r_A = -dC_A/dt = k C_A C_R. The rat — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

Let total concentration C0 = C_A + C_R, which is constant. Rate = k C_A (C0 - C_A). Differentiating with respect to C_A and setting to zero yields max rate at C_A = C0/2. This implies C_A = C_R. Therefore, correct answer is B.
