Question

# (a) For a reaction A + B -->  P, the rate law is given by,r = k [A]1/2 [B]2.What is the order of this reaction?(b) A first order reaction is found to have a rate constant k = 5·5 x 10-14 s-1. Find the half-life of the reaction.

(a)

For A + B-->  P

r = k [A]1/2 [B]2

The order of the reaction =

(b) For first order reaction

k = 5.5 x 10-14 s-1

Half-life period () for the first order reaction
