Question

Consider the evaporation of methanol at 25.0∘c: ch3oh(l)→ch3oh(g). you may want to reference (pages 826 - 829) section 18.9 while completing this problem. part a part complete find δg∘ at 25.0∘c. express the free energy change in kilojoules to one decimal place. δg∘ = 4.3 kj

Answer 1

The reaction is
CH3OH(l)→CH3OH(g)
To calculate ΔG°
ΔG°=ΔG°f of CH3OH(g)-ΔG°f of CH3OH(l)
=162.3kJ/mol - (-166.6kJ/mol
=4.3kJ/mol.
