The molar mass of the repeating unit of polyethylene is 28 grams; the DSC thermogram showed a peak on the cooling side of the cycle at 120° C with a corresponding enthalpy of 25 kJ g-1. Determine (A) the order of this transition & (B) the molar entropy as measured on the cooling side of the cycle. (4 points) (Hint: See Atkins text 129-131 for theory)

Iknow the answer to 13 is b and 14 is d. i just need to know why the correct answers are correct
