Changes in K

So the only thing that changes equilibrium is temperature? If a reactant is removed, the equilibrium would not change? Removing it would only change Q?

[Rachel Lu_dis1H]

Yes. K is the equilibrium constant (or reaction quotient at equilibrium) which is unaffected by changes in concentration. Q is the reaction quotient at anytime.

[Vasiliki G Dis1C]

The equilibrium constant is also unaffected by changes in pressure. As a rule, changes in concentration and pressure do not affect K, and changes in temperature do affect K. If the reaction is endothermic, production formation is favored, and if the reaction is exothermic, reactant formation is favored.

K is a constant, so if concentrations of molecules in the reaction are changed, the reaction quotient eventually go back to whatever K was, unless temperature is changed as well

[Sarah Rutzick 1L]

There is a temperature associated with every K value, which is what allows us to use the K value for all reactions at a given temperature. But, when the temperature changes, we must use the K value associated with that new temperature.
