Question

For the reaction 
what happens to the equilibrium position if the volume decreases?

Quizplus · Accepted Answer

According to Le Chatelier's Principle, when the volume is decreased, the system will try to counteract the change by shifting the equilibrium position in the direction that produces fewer moles of gas. In this case, since there are four moles of gas on the left side of the reaction and only two on the right, the equilibrium will shift to the left, reducing the amount of gas and partially offsetting the volume decrease.
