An unbranched poly-ethylene chain contains 1000 carbon atoms: CH3-[CH2-CH2]499-CH3 There is free rotation around the o bonds that link the carbon atoms. However, steric constraints dictate that each of these torsional angles can only adopt three values (corresponding to the "staggered" orientations 60°, 180°, and 300°). (a) Calculate the entropy of one chain (J K-¹). (b) Calculate the entropy of 3 moles of chains (J K-¹).
