Question
Chapter 5.3, Problem 1PPC
Interpretation Introduction
Interpretation:
The enthalpy change of the given reaction is to be calculated.
Concept introduction:
The change in enthalpy of a reaction, when reactants are converted to products, is the same whether the reaction takes place in one step or multiple steps. This law is known as Hess’s law.
For any process, the change in enthalpy is given by expression:
Here,
If pressure is constant, the change in enthalpy is given by expression:
On reversing any equation, the sign of enthalpy changes.
