The rate of the reaction A + B ___> C + D
Was determined in the experiments at 225 OC. The results are:

Experiment [ A ](M) [B ](M) Initial Rate MS-1
1 0.263 0.826 1.44 x10^-5
2 0.263 0.413 1.44 x10^-5
3 0.526 0.413 5.76 x10 ^ -5

a. Determine the rate law for the reaction
b. Calculate the value of the rate constant at 225 oC
c. Calculate the rate constant of formation of D when [A]=[B]= 0.75M
