The theoretical minimum work required to separate one mole of a liquid mixture at 1 atm, containing 50 mole % each of n- heptane and n- octane into pure compounds each at 1 atm is__________________?
Correct answer: B
Explanation
The minimum work is related to the Gibbs free energy change for separation. For a 50 mole % mixture, this value simplifies to -RT ln(0.5).
