Question

Thermal decomposition of $N_2 O_5 $ occurs as per the equation below:
$2N_2O_5\rightarrow 4NO_2 + O_2$
The correct statement is

• A. $O_2$ production rate is four times the $NO_2$ production rate
• B. $O_2$ production rate is the same as the rate of disappearance of $N_2O_5$
• C. rate of disappearance of $N_2 O_5$ is one-fourth of $NO_2$ production rate
• D. rate of disappearance of $N_2 O_5$ is twice the $O_2$ production rate

Answer 1

Answer: (D)

Rate of disappearance of $N_2O_5$ and rate of formation of $O_2$ must be in $2 : 1 $ ratio as per the stoichiometry of the reaction,
$2N_2O_5\rightarrow 4NO_2 +O_2$
