### Positional (residual) entropy

What exactly is positional/residual energy? and is this what the value you get from boltzmann's equation is?

Hi Hailey!

Residual entropy is a property that arises based on the number of macrostates [that all have equal energies] that are possible in a given system. It is the value that's given by S = kb[ln(W)].

Hope that helps!
