The rate of the reaction :  $2N_2{O}_5\to 4N{O}_2+O_2$ can be written in three ways $\frac{-d\left[N_2{O}_5\right]}{dt}=k\left[N_2{O}_5\right] \frac{d\left[N{O}_2\right]}{dt}=k^{\text{'}}\left[N_2{O}_5\right];\frac{d\left[O_2\right]}{dt}=k^{"}\left[N_2{O}_5\right]$ 

The relationship between k and  $k^{\text{'}}$ and between k and $k^{"}$  are
