As per unique value of reaction rate: - (1/2) ( textd/ textdt) [ textN2 textO5] = (1/1) ( textd/ textdt) [ textO2] ∴ (( textd/ textdt) [ textN2 textO5]/( textd) textdt [ textO2]) = text2: 1 â

Q. $2 N_{2} O_{5} (g) \to 4 (NO)_{2} (g) + O_{2} (g)$

What is the ratio of the rate of decomposition of $N_{2} O_{5}$ to rate of formation of $O_{2}$ ?

$1 : 2$

$2 : 1$

$1 : 4$

$4 : 1$

As per unique value of reaction rate:
$- \frac{1}{2} \frac{d}{dt} [N_{2} O_{5}] = \frac{1}{1} \frac{d}{dt} [O_{2}]$
$∴ \frac{\frac{d}{dt} [ N _{2} O _{5} ]}{\frac{d}{dt} [ O _{2} ]} = 2 : 1$
