Heat of formations of A, B, C, and D, are 1 J, 2 J, 3 J, and 4 J respectively, what is the heat of reaction 3A + 4B -> 2C + D?
(a) -1 J
(b) 1 J
(c) 3 J
(d) 6 J
I got this question by my college professor while I was bunking the class.
This interesting question is from Standard Heat (Enthalpy) of Formation topic in section Application of Energy Balances in the Absence of Chemical Reactions and Energy Balances: How to Account for Chemical Reaction of Basic Chemical Engineering
