Answer :
The gibbs free energy change is zero.
What is gibbs free energy?
The maximum amount of work that a thermodynamically closed system can accomplish at constant temperature and pressure may be calculated using the Gibbs free energy, a thermodynamic potential.
The energy that a material has available for utilisation in a chemical reaction or transformation is known as the Gibbs free energy. Things frequently change into other things that have less Gibbs free energy. The Gibbs free energy change indicates whether a chemical reaction will take place spontaneously or not.
The Gibbs free energy for every equilibrium reaction is zero. The reaction is spontaneous when the Gibbs free energy is smaller than 1. The reaction is not spontaneous in any other case.
