The rate law is determined by comparing the changes in the initial concentrations of the reactants with the corresponding changes in the initial rate. The rate law is found to be:Rate = k[CO][Cl2]^3/2The value of k can be determined by substituting the data from any of the experiments into the rate law and solving for k. Using the first experiment, we get:0.696 = k(0.25)(0.40)^3/2k = 11 M^-3/2s^-1Therefore, the correct answer is A.
