Question

The reaction A + B → products is first order in each of the reactants.

(a) How does the rate of reaction change if the concentration of A is increased by factor 3 ?

(b) What is the change in the rate of reaction if the concentration of A is halved and concentration of B is doubled ?

Answer 1

(a) Rate of reaction = k[A] [B] If the concentration of A is increased by factor 3, then rate of reaction also increases 3 times.

(b) Rate of reaction = k [A] [B] If concentration of A is halved and concentration of B is doubled then,
