Solution

The correct option is B
From the data given, it is found that the reaction is first order w.r.t. $R X$ and first order w.r.t. $N u^{-}$ . So overall order of reaction is 2 i.e. reaction follows $S_{N} 2$ mechanism. Since $S_{N} 2$ reactions proceed through a single transition state and are exothermic. Hence, the correct option is (b).
