Consider 1.00 mole of CO2(g) at 300. K and 5.00 atm. The gas expands until the final pressure is 1.00 atm. For each of the following conditions describing the expansion, calculate q, w, and ΔE. Cp for CO2 is 37.1 J K-1 mol-1, and assume that the gas behaves ideally.
a. The expansion occurs isothermally and reversibly.
b. The expansion occurs isothermally against a constant external pressure of 1.00 atm.
c. The expansion occurs adiabatically and reversibly.
