Rate law expression for the reaction $\mathrm{A}+\mathrm{B}⟶\mathrm{C}+\mathrm{D}$ is $\mathrm{r}=\mathrm{k}[\mathrm{A}{]}^{1/2}[\mathrm{B}{]}^{1/2}$. Starting with initial concentration of one mole of A and B each, what is the time taken for amount of A to become 0.25 moles. Given $\mathrm{k}=2.31\times 10^{-3}{\sec }^{-1}$.
