To determine

Reason behind the criterion for chemical equilibrium expressed in terms of the Gibbs function instead of entropy.

Answer to Problem 1P

The equilibrium criteria can be expressed in terms of properties alone when the Gibbs function is used.

Explanation of Solution

Conclusion:

The reacting system depends upon the heat transfer, change in entropy principle relation requires a detail knowledge about the heat transfer between the system and its surrounding, which is not practical.

Thus, the equilibrium criteria can be expressed in terms of properties alone when the Gibbs function is used.
