When NaNO(3) is heated in a closed vesse...

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

A

Addition of `NaNO_(2)` favours reverse reaction.

B

Addition of `NaNO_(3)` fovours forward reaction

C

Increasing the temperature favours forward reaction.

D

Increasing the pressure favours reverse reaction.

Text Solution

Verified by Experts

The correct Answer is:
C, D
`2NaNO_(3)(s) hArr 2NaNO_(2)(s)+O_(2)(g)`
`DeltaH`=positive, endothermic
Addition of solids does not affect the equilibrium.
Endothermic reaction is favoured by increase in temperature.
Increased pressure shifts the equilibrium in the direction of less gaseous moles.
