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.
