What is meant by free energy of a system ? What will be the direction

1.	What is meant by free energy of a system ? What will be the direction of the chemical reaction when (i) Delta G = 0 (ii) Delta G gt 0(iii) Delta G lt 0 ?
Answer» SOLUTION :Free energy is defined as the energy which can be converted into useful work. (i) `Delta G = 0`, the reaction will be in equilibrium (II) `Delta G gt 0`, the reaction will not take place. (III) `Delta G LT 0`, the reaction will be spontaneous.
