Chemical Equilibrium constant

[Amanda Salgado 3D]

Kc is an equilibrium constant and therefore cannot be changed. Even if the concentration is changed, the constant stays the same, however, if the temperature is changed, does the equilibrium constant change in this case?

Yes, the equilibrium constant Kc is the same for a reaction in an specific temperature, independently of the concentrations. If the temperature changes, K is going to change. Usually if you are not given a temperature, you assume that the reaction is taking place at 25 degrees Celsius.
