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.
Ktrial How can you tell if a system is in equilibrium or not ? Calculate a trial Keq . Use initial concentrations in the equilibrium expression- evaluate .
