Question

The feed of a process simulator is 5 mole with enthalpy 3 J/mole, the heat input is 15 J, and the work performed is 20 J, what will be the product enthalpy if a mole of the product are 2?

(a) 1 J/mole

(b) 2 J/mole

(c) 3 J/mole

(d) 5 J/mole

The question was asked in homework.

I want to ask this question from Unsteady-State Material and Energy Balances topic in division Humidity Charts & their Use, Analysis of the Degrees of Freedom in a Steady – State Process, Solving Material and Energy Balances Using Process and Unsteady State Material and Energy Balances of Basic Chemical Engineering

Answer 1

The correct answer is (d) 5 J/mole

To elaborate: Energy balance, 2*H = 5*3 + 15 – 20 = 10, => H = 5 J/mole.
