The Keq is a constant - a number that does not change Increasing the temperature of an endothermic equilibrium shifts right and increases the Keq Increasing a [Reactant] shifts right and maintains the Keq Only temperature changes the Keq Changing the volume , pressure , or any concentration , does not change the Keq.
