In a vacuum calorimetry experiment, high-energy plasma discharges between Ti(s) electrodes are used — Thermodynamics Chemistry Question
Question
In a vacuum calorimetry experiment, high-energy plasma discharges between Ti(s) electrodes are used to electrolyze water in dilute KOH(aq). During an experiment, the electrical input is 500. kJ and the calorimeter records 610. kJ of heat release into the surroundings. Which best explains this experimental result?
A.✓ Correct
The electrodes undergo partial oxidation, an additional reaction not accounted for in electrolysis.
B.
The system’s large specific heat capacity increases the total heat registered per unit of electrical energy.
C.
The overall process is endothermic, so the surroundings must release heat to maintain equilibrium.
D.
The entropy increase from gas formation causes the system to do work, resulting in additional temperature rise.
