NEET levelSingle correct optionDifficulty 1 of 3ce011

The equilibrium mixture $N X_{2} O X_{4} (g) 2 NO X_{2} (g)$ is compressed to a smaller volume at constant temperature. The equilibrium shifts

Atowards $NO X_{2}$ (forward), the side with more gas moles
Bneither way, since the temperature is constant
Ctowards $N X_{2} O X_{4}$ (backward), the side with fewer gas moles
Dtowards $NO X_{2}$ , since $K_{c}$ increases on compression

Answer: C

Compression raises pressure, which favours the side with fewer moles of gas.

N X_{2} O X_{4}

is 1 mol and

2 NO X_{2}

is 2 mol, so the shift is backward.

K_{c}

remains the same.
