(a)
To determine: The sign of entropy change and enthalpy change for the given process.
Solution: The enthalpy change and entropy change both are positive for the process of sublimation of solid.
Explanation:
The process of sublimation of solid involves the conversion of solid state to the gaseous state. This process always requires heat to proceed further. Therefore, the enthalpy change for this process is always positive.
The change of state from solid to gas involves increase in volume and randomness of the system which leads to the positive entropy change of the system.
Conclusion:
The enthalpy change and entropy change both are positive for the process of sublimation of solid.
