Pressure and equilibrium

[Abigail Menchaca_1H]

What effect does pressure have on the equilibrium of the reaction?

[Jesalynne 2F]

If the pressure is increased the reaction will go towards the side with fewer gas particles. If you decrease the pressure the reaction will go to the side with more gas particles.

If the pressure is increased the reaction will go towards the side with fewer gas particles. If you decrease the pressure the reaction will go to the side with more gas particles.

this is a good quick way to do it, but Dr.Lavelle also emphasized that the reason behind this shift is how pressure changes the concentration, not simply its shift towards less gas particles.

Pressure doesn't affect the equilibrium constant though right? It will only shift it one way or the other?

[Kate Osborne 1H]

You are right, pressure does not affect the equilibrium constant.

yep! heat is the only measure that affects the equilibrium constant

Wait, you mean heat as well as concentration of either the products or the reactants right?

[Kate Osborne 1H]

concentration of either the products or reactants do not change the equilibrium constant, they simply shift the reaction

[Angela Wu-2H]

Pressure does not affect the equilibrium constant. Only temperature changes the equilibrium constant.

[Manav Govil 1B]

Also, solids and liquids are NOT affected by pressure.
