When the temperature falls below 0C , the melting of ice is a non-spontaneous process. What happens if enthalpy decreases? A reaction is favored if enthalpy decreases: There is a bias in nature toward decreasing enthalpy in a system. Reactions can happen when enthalpy is transferred to the surroundings.
