Solution

The correct option is B 1.25 $\times$ 10 $^{- 2}$ mol L $^{- 1}$ S $^{- 1}$ and 3.125 $\times$ 10 $^{- 3}$ mol L $^{- 1}$ S $^{- 1}$
For the reaction
$N_{2} O_{5} (g) ⟶ 2 N O_{2} (g) + \frac{1}{2} O_{2} (g)$
The value of rate of disappearance of $N_{2} O_{5}$ is given $6.25 \times 10^{- 3}$ $m o l L^{- 1} s^{- 1}$ . From the stoichiometry of the reaction.
$\frac{- d [N_{2} O_{5}]}{d t} = \frac{1}{2} \frac{d [N O_{2}]}{d t}$
$⟹ \frac{d [N O_{2}]}{d t} = 2 [\frac{- d [N_{2} O_{5}]}{d t}]$
where $\frac{d x}{d t}$ stands for rate of appearance or disappearance of species $x$ with respect to time.
Therefore rate of formation of $N O_{2}$ and $O_{2}$ is $1.25 \times 10^{- 2}$ $m o l L^{- 1} s^{- 1} C$ and $3.125 \times 10^{- 3}$ $m o l L^{- 1} s^{- 1}$
