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.

Calculate the current density in an electrochemical cell if a current of 2.5 A is passed through a cell containing 0.150 L of a 0.250 M solution of CuSO4 for 2.00 hours. The cathodic half-reaction is Cu2+ + 2e- → Cu and the anodic half-reaction is Zn → Zn2+ + 2e-. The cell has a standard potential of 1.10 V at 298 K. What is the current density of the cell?
