Question

(A) What is rate of reaction? Write two factors that affect the rate of reaction.
(B) For a reaction $A+B⟶P$, the rate is given by

Rate $=k\left[A\right]{\left[B\right]}^2$

(i) How is the rate of reaction affected if the concentration of $B$ is doubled?

(ii) What is the overall order of reaction if $A$ is present in large excess?

Answer 1

(i) Since the given reaction has order two concerning reactant B, thus if the concentration of B is doubled in the given reaction, then the rate of reaction will become four times.

(ii) The overall reaction will be two, because if A is present in excess, then the reaction will be independent of the concentration of A and will be dependent only on the concentration of B.
