Transcribed Image Text:7.35 The vapor pressure of SO,(s) is 1.00 torr at 177.0 K and
10.0 torr at 195.8 K. The vapor pressure of SO,(I) is 33.4 torr
at 209.6 K and 100.0 torr at 225.3 K. (a) Find the temperature
and pressure of the SO, triple point. State any approximations
made. (b) Find AH of fusion of SO, at the triple point.

7.36 The normal melting point of Ni is 1452°C. The vapor
pressure of liquid Ni is 0.100 torr at 1606°C and 1.00 torr at
1805°C. The molar heat of fusion of Ni is 4.2, kcal/mol.
Making reasonable approximations, estimate the vapor pres-
sure of solid Ni at 1200°C.
