Explain how this could be concluded from the data and give a brief argument as to which liquid should be considered the more associated. The different slopes show that the values of D H are different for the two liquids. With the same T b 's but different D H's they cannot both obey Trouton's rule . At 1 atm pressure the two are in equilibrium at 115 o C and at 100 atm pressure the two are in equilibrium at 120 o C. Show which of the forms is the more dense. D H is given as positive in the statement of the problem.
T is of course positive.
Therefore D V must also be positive. Therefore rhombic sulfur is the more dense.
