The vapor pressure of Sn and Pb over pure metals, depending on the temperature, is expressed by the equations:
lg(P0Sn)=-11000/T-1.10*lg(T) 12.86 mm Hg;
lg(P0Pb)=-11130/T-0.985*lg(T) 11.16 mm Hg;
Determine the total and partial pressures of the components over the liquid solution formed by the fusion of 0.1 kg Sn and 0.1 kg Pb at T=1273K.
