volume and K value

Postby sarahsalama2E » Mon Jan 13, 2020 10:54 pm

how does changing the volume affect the equilibrium constant? Say, for example the volume of the container in which the rxn is taking place is halved.

The equilibrium constant is not affected by a change in volume. A change in volume causes the reaction to shift more strongly in one direction to minimize the effect of the change, but does not actually change the equilibrium constant. Changing temperature is the only variation we have learned that can cause the equilibrium constant of a reaction to change.

Changing the volume changes the pressure. This can cause the reaction to lean toward the reactants or products but it does not change the equilibrium constant value.

A change in volume will not affect the equilibrium constant value. It will shift the reaction to favor one side more but will not change K because the temperature is the only factor that is able to change the value of K.
