For the reaction

A + B \longrightarrow C

, the following data were obtained. In the first experiment, when the initial concentrations of both

A

and

B

are

0.1 M

, the observed initial rate of formation of

C

1 \times 10^{-4} \text{ mol litre}^{-1}\text{minute}^{-1}

. In the second experiment when the initial concentrations of

A

and

B

are

0.1 M

and

0.3 M

, the initial rate is

9.0 \times 10^{-4} \text{ mol litre}^{-1}\text{minute}^{-1}

. In the third experiment when the initial concentrations of both

A

and

B

are

0.3 M

, the initial rate is

2.7 \times 10^{-3} \text{ mol litre}^{-1}\text{minute}^{-1}

. (a) Write rate law for this reaction. (b) Calculate the value of specific rate constant for this reaction. (Roorkhee 1987)
