Which would have greater entropy?
1. Br2 or 2Br?
2. CH4 at 25 Celsius or CH4 at 45 Celsius?
3. 1 mol CH4 in 1-L H2O or 1 mol CH4 in 2-L H2O?

This is a very good question. I will be happy to critique your thinking.

I would say first that Br2 would have more than 2Br because don't individual atoms have an entropy of 0? The other two, I have no idea honestly! Please help me with those!

Br2 has more unavailable energy than the atoms, so its entropy is higher.

Use that definition on b.

On c, which has the greater dispersal of CH4 molecules? http://en.wikipedia.org/wiki/Entropy
