When `NaNO_(3)` is heated in a closed vessel, oxygen is liberated and `NaNO_(2)` is left behind. At equilibrium

Options

A. Addition of `NaNO_(2)` favours reverse reaction
B. Addition of `NaNO_(3)` favours forward reaction
C. Increasing temperature favours forward reaction
D. Increasing pressure favours reverse reaction

Answer

C,D

Explanation

`NaNO_(3)(s) hArr NaNO_(2)(s) +O_(2)(g)`
Evidently, rise in temperature will favour forward reaction. The increase of pressure will favour reverse reaction where number of gas moles decreases.
