BRAINCAKEEffects of Temperature on the Position of Equilibrium
The direction in which the equilibrium shifts depends on the sign of ΔH and whether or not the reaction is endothermic or exothermic.

Key terms in this lesson
- Exothermic
- Describes a process in which heat energy is transferred from the system to the surroundings, so the enthalpy change is negative.
- Endothermic
- Describes a process in which heat energy is transferred from the surroundings to the system, so the enthalpy change is positive.
- Position of equilibrium
- The relative amounts of reactants and products present when a reversible reaction has reached equilibrium.
