Delta G for diatomic molecules

Postby Rakhi Ratanjee 1D » Sat Feb 10, 2018 12:13 am

Is the Gibbs free energy for diatomic molecules always equal to zero? Why?

It is only 0 if you are looking at the Gibbs Free Energy of formation due to the standard states of Br, Cl, N, O, and F being diatomic. It is the same for standard enthalpy of formation.

As discussed in class:

Gibbs Free Energy of formation of F2g means what is the Gibbs free energy for:

F2g ---> F2g which has to be zero because both reactant and product are identical.

Hope this helps.

PS. Great answers from students.
