Answer phase questions (i) and (ii)

(i)The Master equation for the change in Molar Gibbs energy can be written as: Gm = Vmp SmT. If two phases are in equilibrium at a given p and T, derive the relationship between p that we exert and T we must make to ensure that the two phases remain in equilibrium: In p2 = In p1 - DvapH/ R ( 1/T2-1/T1) +constant

(ii)The partial molar enthalpy of vaporization for CS₂ is 27.85 kJ mol¹, and the normal boiling point is 319.7 K. Using these values, and assuming that DC_P = 0, compute the percent difference between the normal and standard boiling points for CS₂.
