The increase in Gibbs free energy (in kJ) of 13 g of ethanol (density = 0.78 g cm⁻³), when the pressure is increased isothermally from 1 bar to 3001 bar, is
Answer:
5.00
Solution:
For a (nearly incompressible) liquid, ΔG = VΔP. V = 13/0.78 = 16.67 cm³ = 16.67×10⁻⁶ m³; ΔP = 3000 bar = 3×10⁸ Pa. ΔG = 16.67×10⁻⁶ × 3×10⁸ = 5000 J = 5 kJ.
