The triple point of ammonium is at 196.2 K and 49.92 torr. The vaporisation enthalpy is 24.65 kJ/mol. Calculate the normal boiling temperature of ammonium. Comment the approximations done and their adequacy. With this data, can any magnitude of the sublimation process be calculated?Results: T = 239.3 K, assuming ln p vs 1/T is a straight line in that T range. No.
