WebFeb 19, 2015 · A closed system (such as a chemical reaction in a closed reaction vessel) can exchange energy with the surroundings in the form of work or heat. If you run the process in an irreversible way, more energy will dissipate as heat, and the system will do less work. That is why you would not measure the maximal work in this case. WebAnd we can write 22 Equation (22) is a response function representing the change of total property nM due to addition of a differential amount of species “i” to a finite amount of solution at constant T and P.
