The enthalpy change for the reaction is obtained as - 241.82 kJ/mol.

What is enthalpy change?

ΔH can be determined using calorimetry, measuring the heat flow accompanying the reaction. This information is crucial for understanding the thermodynamics of a chemical process and is often used to design and optimize industrial processes.

We can see that;

Enthalpy of reaction = Enthalpy of products - Enthalpy of reactants

= - 241.82 - 0

= - 241.82 kJ/mol

Thus we can see that the enthalpy change is - 241.82 kJ/mol.
