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

A

Addition of `NaNO_(2)` favours reverse reaction

B

Addition of `NaNO_(3)` favours forward reaction

C

Increasing temperature favours forward reaction

D

Decreasing pressure favours reverse reaction

Text Solution

Verified by Experts

The correct Answer is:
C
`Na NO_(3 (s)) hArr Na NO _(2 (s)) + (1)/(2) O _(2 (g)) , Delta H =+ ve`
Also `K _(P) = (P _(C _(2))) ^( 1//2) ` and thus addition of `NaNO_(3)` or `NaNO _(2)` has no effect.
