Question
Two different crystalline forms of sulfur are the rhombic
form and the monoclinic form. At atmospheric pressure,
rhombic sulfur undergoes a transition to monoclinic when
it is heated above 368.5 K:
S(s, rhombic) → S(s, monoclinic)
(a) What is the sign of the entropy change (AS) for this
transition?
(b) JAH| for this transition is 400 J mol¬1. Calculate AS
for the transition.
