For a given reaction, a change in the pressure may result in a change in the sign of $\Delta$G.

Question

Quizplus · Accepted Answer

According to Le Chatelier's principle, if the pressure is changed in a reaction involving gases, the equilibrium will shift to the side with fewer moles of gas in order to balance the pressure. This means that the sign of ΔG will change if the number of moles of gas in the reaction changes as a result of a pressure change. Therefore, the given statement is true.
