WebHere, the final product possess more Gibbs energy than the individual elements. the above option is not correct. C. 3O 2 →20 3 Here O 3 has more gibbs energy than O 2. the above option is not correct. D. reaction is said to finished when both the reactants and products area at equilibrium state. this state the gibbs free energy is equal to zero. WebAs such, it is a convenient criterion of spontaneity for processes with constant pressure and temperature. The Gibbs free energy, originally called available energy, was developed in the 1870s by the American mathematical physicist Willard Gibbs. In 1873, in a footnote, Gibbs defined what he called the “available energy” of a body as such: ...
