Q. When $NaNO_{3}$ is heated in a closed vessel, $O_{2}$ is liberated and $NaNO_{2}$ is left behind. At equilibrium, (i)Addition of $NaNO_{3}$favours forward reaction (ii) Addition of $NaNO_{2}$favours backward reaction (iii) Increasing pressure favours reverse reaction (iv) Increasing temperature favours forward reaction Correct option is
A) (i), (ii), (iii)
B) (ii), (iii), (iv)
C) (i), (iii), (iv)
D) (i), (ii) (iii), (iv)
Explanation
(d)
$2NaNO_{3} \rightleftharpoons 2NaNO_{2} + O_{2}$
According to Le-Chatelier principle, low pressure, high temperature and addition of $NaNO_{3}$favour forward reaction
