The correct answer is:
$1: 4$
By Differential Rate law;
$\frac{-1}{2} \frac{d\left(N_{2} O_{5}\right)}{d t}=\frac{1}{4} \frac{d\left(N O_{2}\right)}{d t}=\frac{d\left(O_{2}\right)}{d t}$
d $\frac{\text { Rate of formation of } \mathrm{NO}_{2}}{\text { Ratc of formation of } \mathrm{O}_{2}}=\frac{d\left(\mathrm{NO}_{2}\right) / d t}{d\left(\mathrm{O}_{2} / d t\right.}=4: 1$
$\frac{-1}{2} \frac{d\left(N_{2} O_{5}\right)}{d t}=\frac{1}{4} \frac{d\left(N O_{2}\right)}{d t}=\frac{d\left(O_{2}\right)}{d t}$
d $\frac{\text { Rate of formation of } \mathrm{NO}_{2}}{\text { Ratc of formation of } \mathrm{O}_{2}}=\frac{d\left(\mathrm{NO}_{2}\right) / d t}{d\left(\mathrm{O}_{2} / d t\right.}=4: 1$
