Here is a precise question for the student to solve:A chemical reaction occurs in a closed system that results in a change in temperature, but without any change in volume. Using non-equilibrium thermodynamics and irreversible processes, determine the amount of heat absorbed or released by the reaction if the entropy change is known to be 25 J/K.

A chemical reaction was carried out at constant temperature and pressure. The initial concentration of the reactants and products were known. After a certain amount of time, the concentration of the reactants and products were measured. Using non-equilibrium thermodynamics, calculate the magnitude and sign of the entropy change of the system during the reaction.
