(B) The rate law for the reaction is given as $\text{Rate} = k[B]^2$. Since the concentration of $A$ is taken in excess,its concentration remains effectively constant throughout the reaction. The rate of the reaction depends only on the concentration of $B$. The order of the reaction is the sum of the powers of the concentration terms in the rate law expression. Here,the power of $[B]$ is $2$. Therefore,the order of the reaction is $2$.

Consider the gaseous reaction $A_2 + B_2 \rightarrow 2 AB$. The following data was obtained for the above reaction:
$[A_2]_0$ $[B_2]_0$ Initial rate of formation of $AB$ $(mol \ L^{-1} s^{-1})$
$0.1 \ M$ $0.1 \ M$ $2.5 \times 10^{-4}$
$0.2 \ M$ $0.1 \ M$ $5.0 \times 10^{-4}$
$0.2 \ M$ $0.2 \ M$ $1.0 \times 10^{-3}$

The value of the rate constant for the above reaction is:
