5. Iz(s) at 298 K has an enthalpy of sublimation of 56.30 kJ/mol. The Cp.m of the vapor and solid phases at that temperature are 36.9 and 54.4 J/mol.K, respectively. The sublimation pressure at 298 K is 0.30844 torr. Calculate the sublimation pressure of the solid at the melting point (386.6 K) assuming a. that the enthalpy of sublimation does not change with temperature. b. that the enthalpy of sublimation at temperature T can be calculated from the equation AHsub(T)= AHsub(To) + ACP(T - To) assuming that ACp does not change with temperature
