2. Liquid methyl ethyl ketone (MEK) is introduced into a chamber containing nitrogen at 45 C. The pressure rises and then levels off at 1060 mm Hg with liquid still present. For the system at equilibrium, calculate: (a) the number of degrees of freedom according to the Gibbs phase rule. Answer: Not given (b) the partial pressures and mole fractions of each component in the gas phase. Partial Answer: 218.2 mm Hg partial pressure and 0.206 mole fraction for MEK (c) the ratio of mass (g) of MEK vapour to volume (L) of gas. Answer: 0.793 g MEK/L gas
