3 moles of Kr at a pressure of 2 bar and 2 moles of Xe at a pressure of 4 bar are isothermally mixed together at 100°C. The pressure of the mixture is adjusted to 1 bar. 7) Calculate the change in a) entropy, b) enthalpy and c) Gibbs free energy during the mixing. It must be assumed that both gases and the mixture behave as ideal gases.
