Recall that the standard enthalpy of formation (ΔH˚f) refers to the enthalpy change for the formation of 1 mole of a compound from its elements in their standard states.
This means for C2H5OH(l), the reaction involves the formation of 1 mole of C2H5OH(l) from C, H, and O in their standard states.
Write a balanced chemical equation depicting the formation of one mole of C2H5OH(l) from its elements in their standard states.
