Answer:

Hess's law is used as :

(1) To calculate the heat of formation, combustion, neutralisation, ionization, etc.

(2) To calculate enthalpies of reactants and products.

(3) To determine the bond enthalpies.

hope it helped

Answer:

Hess's law is a chemical law that states that the total enthalpy change for a chemical process is the same whether the process takes place in a single step or in a series of steps. This law is based on the principle of conservation of energy, which states that energy can neither be created nor destroyed.

The application of Hess's Law:

  • Calculating the heat of formation.
  • Calculating the heat of combustion.
  • Calculating the heat of neutralization.
  • Calculating the heat of ionization.
  • Calculating the bond enthalpy.
  • Calculating the lattice energy.
  • Determining the spontaneity of a reaction.
  • Predicting the products of a reaction..
