Answer:

∆H or Enthalpy of the reaction

Explanation:

If ∆H is +ve

  • Reaction is exothermic
  • Example:-Combustion, mixing sodium/potassium in water

If ∆H is -ve

  • Reaction is endothermic
  • Ex:-Melting of ice

Answer:

The change in enthalpy that occurs in the process of converting reactants to products in a chemical reaction is called the heat of reaction.
