Fixed point f L A one-dimensional line consists of N number of asymmetric molecules. Consider that the molecules can exchange places with each other laterally. One may think that this would not be possible as the DF molecules would bump onto each other. Let us remove that restriction. The principal mode of vibration of each molecule is w14. In addition, each molecule has two possible orientations as shown by the arrows in the above figure. Consider that the temperature of this system is Thi 1. Calculate the Helmholtz free energy of the system, and then the force needed to keep it in equilibrium. 20pts 2. Calculate the entropy of this system. 20 pts
