Using Hess's law, the enthalpy change of the reaction, ΔH, is -1273.5 kJ/mol.
What is the enthalpy change of the reaction?
The enthalpy change of the reaction is the sum of the heat changes that occur in the reaction as the reactants react to form products.
The enthalpy change is determined from Hess's law which states that the overall change in enthalpy change for a chemical reaction is equal to the sum of the enthalpy changes for each step.
This means that the enthalpy of a reaction which have several intermediate steps is obtained by summing the enthalpies of the intermediate steps.
The enthalpy change, ΔH is determined as follows:
ΔH₁ = -183.6 kJ/mol
ΔH₂ = 361.2 kJ/mol
ΔH₃ = -483.7 kJ/mol
ΔH = {(-183.6) + (361.2) + ( -483.7 × 2)} kJ/mol
ΔH = -1273.5 kJ/mol
Therefore, the enthalpy change of the reaction, ΔH = -1273.5 kJ/mol.
In conclusion, the enthalpy change of the reaction is obtained from the summation of the enthalpies of the individual steps of the reaction.
