Free energy change of mixing two liquid substances is a function of the__________________?
Correct answer: D. All A, B. and C
- A. Concentration of the constituents only
- B. Quantities of the constituents only
- C. Temperature only
- D. All A, B. and C
Explanation
For a mixture, the Gibbs free-energy change of mixing depends on composition or concentrations, the amounts mixed, and temperature through terms such as RTΣnᵢ ln xᵢ. Thus all three listed factors affect it.
