### Resonance and Entropy

Do more resonance structures contribute to a higher residual entropy?

Yes more resonance structures means that it has a higher residual entropy. Since residual entropy S= kblnW in which W is the degeneracy of a molecule, a greater number of possible structures would result in a greater W and thus higher residual entropy. Hope that helps!

### Re: Resonance and Entropy

Since W = microstates^(# of particles), multiple resonance structures have many different microstates. Yeah drawing them out really helps!
