We examine a light-driven dissipative engine, which must necessarily operate far from equilibrium and at a nonzero rate to be capable of providing power and work. The engine's working fluid consists of a buffer gas and the reacting system 2SO3F⇄S2O6F2. We model the concentrations of the reacting system as functions of both temperature and pressure. Piston trajectories maximizing work output and minimizing entropy production are determined for such an engine with the rate-dependent loss mechanisms of friction and heat conduction.
