S=klnW
In general, in what instance will we be required to use this equation?? like in what context?

Re: S=klnW
You would use this equation if the question asked you to calculate absolute entropy (instead of the change in entropy) of a system.

Re: S=klnW
you'd also use this equation if some information is given about W (like any info about number of ways a molecule can exist)

Re: S=klnW
you use S=klnW when you are trying to find the entropy when dealing with the fact that molecules can be rearranged in various ways. You will use the Boltzman's constant and then multiply that by the degeneracy, which show the multiple states the molecules can occupy/be in. This gives you the total disorder for the various states the molecule can be displayed in.
For these kinds of questions, I recommend that you draw out the different states that can be produced when switching around the placement of the individual atoms (which make up the molecule).

Re: S=klnW
Can someone explain what residual entropy is and is it found from just using this equation?

Re: S=klnW
Residual enthalpy can be calculated when a reaction is taking place at a very low temperature almost close to 0

Re: S=klnW
This is total entropy, not change in entropy which is what we normally tend to calculate. You would use this when given a number of molecules and the possible orientations they can lay in and such. For example if a solid had 64 molecules and the molecules can like in any 4 directions, W= 4^64
