How does volume effect Le Chatelier's principle?

Answer 1

According to this principle, systems that are in equilibrium will counteract external stress in order to return to equilibrium.

Therefore, when a container's volume is involved in a gas reaction,

#3H_2(g) + N_2(g) to 2NH_3(g)#

In the former scenario, the system will shift to the left and decrease the number of moles of gas present; in the latter case, it will increase the number of moles of gas present.

Volume changes do not significantly affect Le Chatelier's principle for reactions not involving gases. For gas-phase reactions, an increase in volume favors the side with more moles of gas.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
