Consider the following data for the reaction A+B=Products

initial concentration (A) Initial concentration (B) Initial rate(mol L-1s-1

0.10M 1.00M 2.1x10^-3

0.20M 1.00M 8.4x10^-3

0.20M 2.00M 8.4x10^-3

Determine rder of the reaction w.r.t A & w.r.t B & the overall order of the reaction.Also calculate rate constant.

Dear Ranjita,

Since on doubling the conc of A , the rate of reaction becomes 4 times , So the order is 2 wrt A

And is independent of any change in conc of b so order is 0 wrt B.

W.r.t A=2,B=0,Overall=2,Rate constant=0.21
