SUMMARY
The discussion centers on the calculation of Gibbs free energy using the equation ##\Delta G = \Delta G^0 + RT \ln(c_B/c_A)##, where ##c_A## and ##c_B## represent the concentrations of species A and B, respectively. The participant expresses confusion regarding the correct answer to a multiple-choice question, indicating that without clear units, multiple answers could be valid. The key answer is identified as option a, but the participant highlights the importance of understanding the context of the units involved in the calculations.
PREREQUISITES- Understanding of thermodynamics principles, specifically Gibbs free energy.
- Familiarity with the equation for Gibbs free energy and its components.

I think that ##\Delta G = \Delta G^0 + RTln(c_B/c_A)##, where ##c_A## and ##c_B## are the concentrations of species ##A## and ##B##, respectively.

As long as it is not clearly stated in what units given answers are, every one of them can be correct (well, perhaps the only thing that allows differentiation between them is the sign).
