MCQ- What is the Gibbs free energy value?

Click For Summary

Discussion Overview

The discussion revolves around the calculation of Gibbs free energy, specifically in the context of a multiple-choice question (MCQ). Participants explore the formula for Gibbs free energy and the implications of unit specifications on the correctness of answers.

Discussion Character

  • Exploratory, Debate/contested, Homework-related, Mathematical reasoning

Main Points Raised

  • One participant questions their understanding of the correct answer based on the provided key, indicating potential confusion or error in their reasoning.
  • Another participant presents the formula for Gibbs free energy, suggesting that it incorporates the standard Gibbs free energy change and the concentrations of reactants and products.
  • A different viewpoint emphasizes that without clear unit specifications, multiple answers could be considered correct, highlighting the importance of context in interpreting the results.
  • A brief acknowledgment of gratitude is expressed, indicating engagement but not contributing to the technical discussion.

Areas of Agreement / Disagreement

Participants do not reach a consensus; there are competing views regarding the correctness of the answers and the interpretation of the Gibbs free energy formula.

Contextual Notes

There is a lack of clarity regarding the units of measurement for the answers, which affects the ability to determine the correctness of the options presented in the MCQ.

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).
