Quizplus · Accepted Answer

The rate law for the given reaction is rate = k[A][B]^2. The initial concentrations of A and B are given: [A] = 0.200 M and [B] = 0.500 M. Substituting these values into the rate law, we get:

rate = k(0.200 M)(0.500 M)^2 
      = k(0.050 M^2)

To determine the value of k, we need to use experimental data. However, the question only asks for the initial rate of C production, which is defined as the rate of the reaction at t = 0. At t = 0, the concentrations of all reactants remain unchanged, so we can use the rate law with the initial concentrations of A and B:

initial rate = k(0.200 M)(0.500 M)^2 
            = k(0.050 M^2)

Therefore, the initial rate of C production is proportional to k(0.050 M^2). The correct answer choice is A).
