###### Question details

1. A common model for polymer configurational entropy considers each link in the polymer chain backbone to have only three possible values (the three staggered angles, 60, 180, 300) of χ, the dihedral angle, all with the same probability and all independent of each other. For a polymer with N monomer units, there are N-1 links. One “configuration” of the polymer means one possible choice for all the N-1 dihedral angles, χ1,χ2,...,χN-1.

d) Find an expression for the entropy change for the polymer in going from a state with only two angles per link to one with three.
