Topic 13 - Entropy

Entropy

1. Interpret the relationship between entropy and spontaneous change.
2. Recall the formula for calculating the entropy change in a reaction.
3. Calculate the standard entropy change in a system for a chemical reaction from standard entropy data.
4. Recall that the standard entropy of a substance is dependent on the material’s physical state.
5. Predict the relative entropies of different substances from their physical states.
6. Recall the formula for the entropy change of a substance in terms of temperature and enthalpy.
7. Understand that the feasibility of a reaction depends upon the balance between the entropy change of the surroundings and that of the system.
