Comment on "Validity of path thermodynamic description of reactive systems: Microscopic simulations".

Abstract

The assertions made in a recent paper [Phys. Rev. E 107, 014106 (2023)10.1103/PhysRevE.107.014106] regarding the validity of path thermodynamics are ill founded and contradict well-known results. Following up on a previous Comment, I show that, for both models of chemical reaction networks considered in the aforementioned paper, path thermodynamics yields values of the entropy production rates fully consistent with those expected from standard chemical thermodynamics in the large-system limit.
