3.4 Analyze the enthalpy of mixing S23 CHEE610 Homework \#2 (total 100 pts) Due: March 14, 2023 at 9:30 am in Classroom 3. Mixing of Gases at Fixed Total Volume and Temperature. In this case we will assume that the individual gases are at the same temperature, but are initially at different pressures. The following shows a schematic of the mixing. The initial pressures of the gases are: PA,PB,PC and PD. The final pressures of the gases are: pA,pB,pC and pD. Initial 3.1 Write the initial Gibbs free energy and final Gibbs free energy 3.5 Analyze the entropy of mixing 3.2 Analyze the total pressure after mixing 3.3 Analyze Gibbs free energy of mixing
