We’re being asked to determine the balanced chemical equation for the formation of one mole of C2H4 (g) from its elements in their standard states
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.
Write an equation for the formation one mole of C2H4 (g) from its elements in their standard states. Write any reference to carbon as C(s).
