Interpretation: The enthalpy change at constant pressure is to be found.
Concept introduction:
The standard enthalpy of formation is the amount of energy released or consumed when one mole of a substance is formed under standard conditions from its pure elements.
Standard temperature and pressure conditions are 298 K and 1 atm.
The enthalpy of formation for an element in its elemental state or naturally occurring state will always be zero because it takes no energy to form a naturally occurring compound.
