Question

According to Le-Chatelier's principle, which of the following occurs when you compress a system containing at least one gas species?

• A. Shifts to favor the side with less moles of gas.
• B. Shifts to favor the side with more moles of gas.
• C. Remains at equilibrium.
• D. Not enough information to determine.

Answer 1

The correct option is A Shifts to favor the side with less moles of gas.

According to Le-chatelier's principle, when a system is compressed, its volume decreases, so system will try to minimize the effect by increasing the partial pressure of the all the gases present in the system. Therefore, the system will act to try to nullify the pressure by decreasing the moles of gas.
