Question

Which of the following is required for the calculation of heat of reaction in the energy balance?

(a) Heat of solution at reference state

(b) Heat of dissolution at reference state

(c) Heat of formation

(d) All of the mentioned

This question was posed to me during an internship interview.

This intriguing question comes from Effects of Mixing into Energy Balance topic in portion 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

Answer 1

The correct answer is (d) All of the mentioned

Easy explanation: Heat of solution at reference state, Heat of dissolution at reference state and heat of formation all are required in the calculation of Heat of reaction.
