Comment on the thermodynamic calculation using the non-standard equilibrium constant re Jemutai-Kimosop et al. (2020) and Conde-Cid et al. (2019)

Abstract

This comment discussed the calculation of thermodynamic parameters about the paper of Jemutai-Kimosop et al. (2020) and Conde-Cid et al. (2019). Although these articles are valuable, in these cases, the equilibrium constant (K), which is used for the calculation of thermodynamic parameter is incorrect. The root reason for the errors in both articles is that the non-standard equilibrium constant was used to calculate the thermodynamic parameter, which is contrary to the principle of thermodynamics. This comment provided a correct method for the calculation of the standard equilibrium constant by using the distribution coefficient and Langmuir equation. This note can avoid the misuse and propagation of the incorrect equation in the area of adsorption thermodynamics.
