K changing with temperature

Postby juliasloan_4g » Mon Jan 14, 2019 3:57 pm

Could someone please explain why Kp changes when temperature is changed but not when the pressure is changed. Thanks

Equilibrium constants change from temperature. Other changes, like changing concentration, will shift a reaction out of equilibrium, but the reaction will eventually return to equilibrium with the same K. Only temperature permanently alters a K. Changing pressure does not affect K, but changing concentration can shift a reaction.

Lavelle told us in class that pressure doesn't affect K. K is only changed when the temperature changes

K is unaffected by pressure but affected by temperature.
