Question: Dry ice (solid CO2) spontaneously sublimes at -78.5C. a. If the enthalpy change associated with this process is 26.1 kJ/mol, what is the entropy change

Dry ice (solid CO2) spontaneously sublimes at -78.5C.

a. If the enthalpy change associated with this process is 26.1 kJ/mol, what is the entropy change of the process at this temperature?

b. The standard molar entropy of gaseous carbon dioxide is 213.8 J/molK. How many microstates would one molecule of CO2 gas have under standard conditions?

c. Would you expect dry ice to have a higher or lower standard molar entropy than gaseous carbon dioxide? Explain.
