Question

The reaction 2Mg(s)+O2(g)→2MgO(s) has a free energy ΔGrxn=−597 kJ/mol under standard conditions. What is the free energy of formation of MgO?

Answer 1

Answer:

-298.5 kJ/mol

Explanation:

-298.5 kJ/mol

The given reaction provides the Gibbs free energy of formation for the formation of two moles of MgO. Therefore, the Gf foror one mole is half that amount.
