Question

For the reaction A + B → products, the following initial rates were obtained at various given initial concentrations

S.No.	[A] mol / L	[B] mol / L	Initial rate M/s
1.	0.1	0.1	0.05
2.	0.2	0.1	0.10
3.	0.1	0.2	0.05

Determine the half-life period.

Answer 1

rate =  k [A]^x [B]^y 

It is a first order reaction.
