Question

For the first order decomposition reaction of $N_{2} O_{5}$ , it is observed that
$(i) N_{2} O_{5} (g) \to 2 N O_{2} (g) + \frac{1}{2} O_{2} (g); \frac{- d [N_{2} O_{5}]}{d t} = k [N_{2} O_{5}] (i i) 2 N_{2} O_{5} (g) \to 4 N O_{2} (g) + O_{2} (g); \frac{- d [N_{2} O_{5}]}{d t} = k^{'} [N_{2} O_{5}]$
Which of the following is true?
