Abstract : We are pleased to report extensive progress in a number of areas in thermodynamics kinetics, and stochastic theories in non-linear chemical reactions far from equilibrium. Research includes both theoretical and experimental studies. Specific areas of research include the following: (1) Thermodynamic and Stochastic Theory of Electrical Circuits; (2) Thermodynamic and Stochastic Theory for Non-equilibrium Systems with Multiple Reactive Intermediates: The Concept and Role of Excess Work; (3) The relation of Fluxes and forces to work in Nonequilibrium Systems; (4) Multiple Steady States in Coupled Flow Tank Reactors; (5) Thermodynamic and Stochastic Theory for Non-ideal Systems Far from Equilibrium; (6) Thermodynamic and Stochastic Theory of Reaction Diffusion Systems with Multiple Stationary States; (7) Stationary Probability Distribution Near Stable Limit Cycles Far from Hopf Bifurcation Points; (8) Fluctuation-dissipation Relations for Chemical Systems; (9) Thermodynamic and Stochastic Theory of Nonequilibrium systems: Fluctuation Probabilities and excess Work; (10) Thermodynamic and Stochastic Theory of Non-equilibrium Systems: A Lagrangian Approach to Fluctuations and Relation to excess work. Experiments on Relative Stability in the Bistable Multivariable Bromate-Ferroin Reaction. (AN)
