Change in temperature and K

Postby sallina_yehdego 2E » Mon Jan 14, 2019 11:02 pm

Why does a change in temperature affect K and not a change in pressure or concentration?

If you increase the temperature of a reaction, you drive the equilibrium backwards (in the endothermic direction), and therefore increase the concentration of reactants and decrease the concentration of products. The two are inherently connected!

This does not apply to either pressure or concentration.

Think of it like K will determine how pressure/concentration changes (because K is constant, pressure and concentration must increase or decrease to have [product]/[reactant] equal K), while temperature is what determines K.
