Why does only Temperature change K?

[Andrew F 2L]

Why is it that temperature can only change the equilibrium constant? Would changing concentrations also change the equilibrium constant as well?

K is very energy dependent, because adding or taking away heat from a chemical reaction would change the overall kinetics of the reaction itself, and thus affect K. Changing the concentrations would not change K, as increasing the concentration of products would result in an increase in concentration of the reactants as well, and thus preserving the [Products]/[Reactants] ratio, not affecting K at all.

Temperature changes the amount of energy in a reaction, altering the overall thermodynamics of the reaction. Changing the concentrations of reactants or products would only change the Q, not the overall equilibrium constant.
