Changing K

Postby McKenna_4A » Tue Jan 21, 2020 12:16 pm

Which factors can actually change K in a reaction? I'm fairly sure temperature will, however I'm getting mixed messages about pressure having an effect as well.

As far as we know, temperature is the only relevant factor that can change K. Pressure cannot change K, whether you change the pressure by adding more gases like He2 or by changing the volume. At most, changing the pressure can throw the reaction off equilibrium, but the K value is the same.

Because K is a constant, the only factor that can change it is temperature, as certain reactions will go further toward completion when heat is added and vice versa.

I think that temperature is the only relevant factor that changes K.

Since changing temperature is the only thing that affects changing K, it becomes a different reaction, right?

Changing temperature does not make it a different reaction it simply makes the reaction go more to completion which therefore changes K.

Temperature is the only factor that can change K. Changes in concentration or pressure does not affect K.

Only temperature can change the value of K.

Only temperature can change K. (Pressure, volume, etc. can change the concentrations of reactants/products, but cannot change the equilibrium constant).

K is changed by change in temperature.

K is changed by temperature, but not pressure or adding/removing reagents/compression.

Only increasing or decreasing temperature can change the value of K.
