TermDefinition
Closed systemneither matter nor energy can be lost or gained from the system, macroscopic poperties remain constant
The equilibrium constantthe concentration of products divided by the concentration of reactants
the magnitude of the equilibrium constantthe magnitude is related to the position of equilirium
Le Chatelier's Principleif a system at equilibrium is subjected to a small change the equilibrium tends to shift to minimize the effect of the change
homogeneous reactionreactants and products are the same phase
change in concentrationthe equilibrium shifts to the opposite side
Change in pressureincreasing the pressure will shift the equilibrium to the side with less volume
Change in temperature (exothermic)if heat is taken away forward reaction is increased
change in temperature (endothermic)if heat is taken away the equilibrium will shift to the left
adding a catalystwill increase the rate at which the quilibrium is reached, but has no value on the equilibrium position
