![In refineries, alkylbenzene and alkylnaphthalene streams re-
sult from catalytic cracking operations. They can be hydrodeal-
kylated to yield valuable products such as benzene and
naphthalene. At 25°C, solid naphthalene (normal melting point
80.3°C) has the following solubilities in liquid solvents including
benzene [Naphthalene, API Publication 707, Washington, DC (Oct.
1978)]:

For each solvent, compute the activity coefficient of naphthalene
in the solvent phase using the following equations (with T in K) for
the vapor pressure in torr of solid and liquid naphthalene:
