Question

Define standard enthalpy of formation. How is it useful to calculate standard reaction enthalpy?

Answer 1

Hey,

STANDARD ENTHALPY OF FORMATION:-

Thestandard enthalpy of formation ( Δ H f ∘ ) is defined as the enthalpy change for creating one mole of a compound from elements in their standard states. ... Enthalpies (or heats) of formationare extremely useful in calculating reaction enthalpies.
