Problem

The rate of a reaction starting with initial concentration of

2 \times 10^{-3} M

and

1 \times 10^{-3} M

are equal to

2.40 \times 10^{-4} M \text{ sec}^{-1}

and

0.60 \times 10^{-4} M \text{ sec}^{-1}

respectively. Calculate the order of reaction w.r.t. reactant and also the rate constant.
