\mathrm{\text { Reaction:- } 2 A+B_2 \rightarrow 2 A B}

As the reaction is elementary, the rate of reaction is 

\mathrm{r=k \cdot[A]^2\left[B_2\right]}

On reducing the volume by a factor of 5 , the concentrations of \mathrm{A \ and \ B_2}  will become 5 times and hence, the rate becomes

\mathrm{5^2 \times 5=125 \text { times of initial Rate }}
