Question:

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 △ S, D△ surr, and △S univ. 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
