The standard free energy is the difference between that of products and reactants. The value of G has a greater influence on the reaction been considered.

Explanation:

The Gibb's free energy also referred to as the gibb's function represented with letter G. it is the amount of useful work obtained from a system at constant temperature and pressure. The standard gibb's free energy on the other hand is a state function represented as Delta-G, as it depends on the initial and final states of the system. The spontaneity of a reaction is explained by the standard gibb's free energy.

If Delta-G = - ve (the reaction is spontaneous) if Delta - G = + ve (the reaction is non-spontaneous) if Delta-G = 0 (the reaction is at equilibrium)

Use this hints for any reaction involving the Gibb's free, Enthalpy and entropy.
