The decomposition of $N_2O_5(g)$ is a first order reaction with a rate constant of $5 \times 10^{-4} s^{-1} \ at \ 45^\circ C$, i.e., $2N_2O_5(g) \rightarrow 4NO_2(g) + O_2(g)$. If initial concentration of $N_2O_5$ is $0.25M$, calculate its concentration after $2\ min$. Also, calculate half- life for decomposition of $N_2O_5(g).$
