Air is a mixture of gases with the following mass percentagecomposition: 75.52% N2, 23.15% O2, 1.28% Ar, and 0.046% CO2.
A. What are the partial pressures of N2, O2, Ar, and CO2 whenthe total pressure is 1.100 atm?
B. Calculate the molar Gibbs energy of mixing of air at 25Cassuming ideal gas behavior.
C. Determine the molar enthalpy of mixing and the molar entropyof mixing for air at 1.100 atm and 25C.
D. Is the mixing of pure gases to form air spontaneous? How doesthe total pressure affect spontaneity of gas mixing?
