AI Article Synopsis
- The article discusses the recovery of conservation laws and the derivation of the H-theorem in kinetic equations with gradient corrections.
- The authors argue that this approach has flaws, resulting in omitted terms related to energy and momentum balance.
- Consequently, these inaccuracies lead to a mismatch with the correlation entropy established in the Enskog equation.
Article Abstract
The article [Phys. Rev. E 96, 032106 (2017)10.1103/PhysRevE.96.032106] recovers conservation laws and derives the H-theorem for the kinetic equation with gradient corrections. Here we show that this approach is not valid, leading to missing terms in the balance of energy and momentum and to disagreement with correlation entropy known from the Enskog equation.

The Comment's author argues that a correct description of reactive systems should incorporate an explicit interaction with reservoirs, leading to a unified system-reservoir entity. However, this proposition has two major flaws. First, as we will emphasize, this entity inherently follows a thermodynamic equilibrium distribution.
