I am wondering how to go about getting the answer to this equation, is there an equation that is used or what?

16. Determine the rate law and the value of k for the following reaction using the data provided.CO(g) + Cl2(g) - COC12(g)[CO]i (M)[C12]i (M)Initial Rate (M-1s-1)0.250.400.6960.250.801.970.500.803.94A) Rate = 11 M-3/2s-1 [CO][C12]3/2D) Rate = 4.4 M-1/2s-1 [CO][C12]1/2B) Rate = 36 M-1.8s-1 [CO][C12]2.8E) Rate = 18 M-3/2s-1 [CO]2[C12] 1/2C) Rate = 17 M-2s-1 [CO][C12]2
