Enthalpy changes for solids and solutions

Define standard enthalpy change of formation (ΔfH⊖\Delta_{\text{f}}H^\ominusΔf​H⊖).

A

Enthalpy change when one mole of a compound is formed from its gaseous atoms in their standard states under standard conditions.

B

Enthalpy change when one mole of a compound is broken into its elements in their standard states under standard conditions.

C

Enthalpy change when one mole of a compound is formed from its elements in their standard states under standard conditions.

D

Enthalpy change when one mole of a compound is formed from its constituent compounds in their standard states under standard conditions.
