The element, s (sulfur), undergoes a phase transition from a rhombic form to a monoclinic form at 95.4°c. if δhtransition=0.38 kj mol-1, calculate δstransition under the above conditions. show all working. (ii) monoclinic sulfur is known to melt at 119°c. given δhfusion=1.23 kj mol-1, calculate, showing all working, δsfusion. (iii) given the s occurs as s8 in solid or liquid forms, convert the values of the enthalpy and entropy of fusion above to those expected for s8.
