Question:medium
The rate of reaction $A \rightarrow P$ is $1.25 \times 10^{-2}$ mol dm$^{-3}$ s$^{-1}$ when $[A] = 0.5$ M. Calculate the rate constant if the reaction is second order in A.
The rate of reaction $A \rightarrow P$ is $1.25 \times 10^{-2}$ mol dm$^{-3}$ s$^{-1}$ when $[A] = 0.5$ M. Calculate the rate constant if the reaction is second order in A.
Show Hint
For $n^{th}$ order reactions, the units of $k$ are (mol dm$^{-3}$)$^{1-n}$ s$^{-1}$. For $n=2$, it is mol$^{-1}$ dm$^{3}$ s$^{-1}$.
