Le Chatelier's Principle

Postby Jessica Castellanos » Mon Jan 20, 2020 10:47 am

Just to make sure, changing the pressure does affect the way the equilibrium will shift only if the change in pressure is from the change in volume?

That is correct. Changing pressure only causes an equilibrium shift when the change in pressure comes from a change in volume, since this also leads to a change in concentration for the reactants and products. Changing pressure through the addition of an inert gas which doesn't affect concentrations of reactants or products will not cause a shift in equilibrium.

Also, if the moles of gas on either side of the reaction (and therefore space taken up in the volume) are equal than a change in pressure has no effect
