Vedclass · Answer

(A) $1$. The half-life of a reaction is independent of the initial concentration for a first-order reaction. Since the half-life remains unchanged when the concentration of $A$ is doubled,the order of reaction with respect to $A$ is $1$.$2$. When the concentration of $B$ is doubled,the rate increases by a factor of $2$. This indicates that the order of reaction with respect to $B$ is $1$.$3$. The overall order of the reaction is $n = 1 + 1 = 2$.$4$. The unit of the rate constant for a reaction of order $n$ is $(mol \, L^{-1})^{1-n} \, s^{-1}$.$5$. For $n = 2$,the unit is $(mol \, L^{-1})^{1-2} \, s^{-1} = (mol \, L^{-1})^{-1} \, s^{-1} = L \, mol^{-1} \, s^{-1}$.

For the reaction $2A + B \rightarrow \text{Product}$,the half-life remains unchanged when the concentration of $A$ is doubled. When the concentration of $B$ is doubled,the rate of reaction increases by a factor of $2$. What is the unit of the rate constant for this reaction?
