Explanation:
Energy change associated with phase change in substances is either endothermic (energy added to system) or exothermic (energy removed from system). Condensation is but one term in six (6) describing phase change occurring when energy change is involved. The following table, in general, summarizes the related effects of energy change as applied to phase change.
Process Phase Change Energy Change*
Condensation gas => liquid Exothermic
Evaporation liquid => gas Endothermic
Freezing liquid => solid Exothermic
Melting solid => liquid Endothermic
Sublimation solid => gas Endothermic
Deposition gas => solid Exothermic

* Energy Change terms:
Endothermic => Addition of heat energy
Exothermic => Removal of heat energy
To be at equilibrium means the rate of the forward reaction must equal the rate of the reverse reaction. This does not mean that there should be an equal amount of both products and reactants when at equilibrium. It simply means the RATES of the forward and the reverse are equal to one another.
