Free energy change of mixing two liquid substances is a function of the

A. Concentration of the constituents only

B. Quantities of the constituents only

C. Temperature only

D. All of the above

Answer: Option D

Solution(By Examveda Team)

$$\Delta {g^{mix}} = RT\sum\nolimits_{i = 0}^2 {{n_i}\ln {x_i}} $$
Hence, we can say free energy is dependent on concentration, temperature, quantities of constituents.
