Adecorative "ice" sculpture is carved from dry ice (solid co2) and held at its sublimation point of –78.5°c. consider the process in which a co2 sculpture, weighing 389 g, sublimes on a granite tabletop. the temperature of the granite is 12.0°c and the process occurs reversibly. assume a final temperature for the co2 vapor of –78.5°c. the enthalpy of sublimation of co2 is 26.1 kj/mol. calculate the entropy of sublimation for carbon dioxide (the system) j/kmol
