Nonequilibrium Thermodynamics of Chemical Networks — •Riccardo Rao and Massimiliano Esposito — University of Luxembourg, Luxembourg, Luxembourg

Chemical Networks (CN) are large sets of coupled chemical reactions where some of the species are externally controlled. Cell metabolism and biochemical signal transduction networks are notable examples of CN. We present a rigorous nonequilibrium thermodynamic description of CN in terms of deterministic rate equations. Our description is inspired by Stochastic Thermodynamics and is based on Chemical Reaction Network Theory. The energy and entropy balances of CN are derived and a nonequilibrium Gibbs free energy is introduced. This latter is related to the chemical work necessary to create nonequilibrium states and to the driving work necessary to control the network far from equilibrium. We finally discuss these different forms of work in the stochastic framework.
