Decreasing the volume of the system below causes the reaction to shift towards the right.

Question

Quizplus · Accepted Answer

According to Le Chatelier's principle, a decrease in volume (pressure) causes the reaction to shift towards the side with fewer moles of gas. If the reactants and products have different numbers of moles of gas, then the reaction will shift towards the side with fewer moles of gas upon a decrease in volume. This corresponds to the side of the reaction with more molecules, i.e., the right side. Therefore, decreasing the volume of the system causes the reaction to shift towards the right.
