Partial Pressures

Postby Sara Lakamsani 4D » Sat Mar 16, 2019 10:12 pm

When applying Le Chateliers to partial pressures, should we think about it in terms of compressing the entire reaction or changing the amount of a given reactant or product present?

Le Chatelier's principle is generally referring to equilibrium so you should treat it like an amount of a given substance, which is represented by the partial pressure.

Is anyone able to give a simple, direct description of this concept?

When it comes to partial pressures, there are two ways that a system at equilibrium can change.
Either
1) The entire volume of the container is being reduced. This would increase pressure on all of the molecules in the system and it would respond by shifting the equilibrium to whichever side has a smaller number of gas molecules.
2) There is a change in the amount of a certain gas. You would treat this as if the concentration was increased or decreased and the equilibrium should react in the same way.
