underset( g ) N 2 O 4 leftharpoons 2 NO 2( g ) ; QC =([ NO 2]2/[ N 2 O 4]) When inert gas is added under the condition of constant pressure, volume increases. Hence, QC decreases and reaction moves in forward direction to achieve equilibrium.

Q. Assertion: Adding an inert gas todissociation equilibrium of gaseous $N_{2} O_{4}$ at constant pressure and temperature increases the dissociation.
Reason: Molar concentration of the reactants and products decreases on the addition of inert gas.

If both A and R are correct and R is the correct explanation of A.

If both A and R are correct but R is not the correct expalnation of A.

A is true but R is false.

A is false but R is true.

$(g) N_{2} O_{4} ⇌ 2 N O_{2} (g); Q_{C} = \frac{[ N O _{2} ] ^{2}}{[ N _{2} O _{4} ]}$
When inert gas is added under the condition of constant pressure, volume increases.
Hence, $Q_{C}$ decreases and reaction moves in forward direction to achieve equilibrium.
