I have been asked this question during an online interview.
This is a very interesting question from Ideal Reversible Processes topic in section Energy Balances that Include the Effects of Chemical Reaction, Ideal Processes, Efficiency and the Mechanical Energy Balance and Heats of Solution and Mixing of Basic Chemical Engineering
