Entropy Definitions

Postby Hannah Chew 2A » Mon Feb 12, 2018 9:48 am

What is the difference between 1) standard molar entropies 2) standard molar entropies for formation 3) residual entropies?

I am actually not sure if there is a standard molar entropy of formation?---I thought it was just standard molar entropy for a substance...
for residual entropy, it is the entropy remaining when the temperature is 0K. unless the substance is a perfect crystal at 0k, it will have a residual entropy.

^ 1) But what is the difference between standard molar entropy and residual entropy?
2) In the solution manual, 9.55 looks at the difference between formation and molar entropy, so what is the difference?
