(a) Use the Clausius-Clapeyron equation and calculate the vapor pressure (mm Hg) of fluoroethane at
-80 °C, given that the vapor pressure is 400. mm Hg at a temperature of -46 °C. The enthalpy of vaporization of
fluoroethane is 23.0 kJ/mol.
(b) Calculate the enthalpy of vaporization for a compound if its vapor pressure is 70 mm Hg at -50 °C
and 323 mm Hg at -28 °C.
Examining the crystal structure of CsCl (Caesium Chloride), the Cs+ions form the 8 corners of a cube
and the Cl−ion is a the center of the cube. From first-principles calculation, it was determined that the
lattice constant of CsCl is 4.209 ̊A. (a) Calculate in detail the electrostatic force exerted by all the Cs+
atoms to the Cl−atom; (b) Assuming that 1 Cs+atom is missing in crystal structure (crystal is said
to have a defect), calculate in detail what will be the net electrostatic force on the Cl−ion due to the
remaining Cs+ions.
