Question: An equimolar mixture of carbon dioxide and water vapor at 1 atm and 60C enter a dehumidifying section where the entire water vapor is condensed

An equimolar mixture of carbon dioxide and water vapor at 1 atm and 60°C enter a dehumidifying section where the entire water vapor is condensed and removed from the mixture, and the carbon dioxide leaves at 1 atm and 60°C. The entropy change of carbon dioxide in the dehumidifying section is
(a) -2.8 kJ/kg • K (b) -0.13 kJ/kg • K
(c) 0 (d) 0.13 kJ/kg • K
(e) 2.8 kJ/kg • K
