If you INCREASE the pressure with the following equation (assume all are gases)

A + B --> AB.

Which direction will the equilibrium shift to restore balance?

1 answer

If you increase the pressure, the equilibrium will shift in the direction which has fewer moles of gas. In this case, when A and B combine to form AB, the moles of gas decreases. Therefore, the equilibrium will shift towards the product AB to balance the pressure.
