6C(s)+3H2(g)→C6H6(l)
Concept Introduction:
At standard states, the free energy charge which is responsible for the production of 1 mole of a molecule from its elements is known as standard free energy of formation and it is represented by ΔGfo.
If the value of ΔG298o is more than zero, then non-spontaneous will be the reaction whereas If the value of ΔG298o is less than zero, then spontaneous will be the reaction.
The mathematical expression for ΔGfo at standard state is given by:
ΔG298o=ΔH°-TΔS° or,
ΔG°=ΔG°298=∑nG°298(products)−∑pG°298(reactants)
Where, n and p represents the coefficients of reactants and products in the balanced chemical equation.
