Convert the value of the entropy of transition in part above to those appropriate for S Express your answer to two significant figures and include the appropriate units astransition= 13.14 mol K Submit My Answers Give Up Incorrect; Try Again

Explanation / Answer

Delta S transition= Deltah H transition / Delta T transition

= 0.38 kJ mol^-1 / (273.15+95.4)K

= 1.0 J K^-1 m^-1

================================================

Delta S fusion = Delta H fusion / Delta T fusion

= 1.23 kJ mol^-1 / (273.15+119)K

=3.14 J K^-1 m^-1

=======================================

Each of the delta in parts (a) and (b) should be multiplied by 8.

transition delta S = 8.2 J K^-1 mol^-1 -------------------ANSWER

fusion delta S = 25.1 J K^-1 mol^-1

====================================
