Exothermic reactions proceed with release of heat (the opposite is endothermic). Accordingly, the reaction shows a negative reaction enthalpy or phase transfer enthalpy.

Examples for exothermic reactions or phase transfers:

  • Solidification of melt
  • Condensation of steam
  • Burning of coal to carbon dioxide
  • Oxyhydrogen reaction
  • Hydration of lime
