Question #4\ A vapor mixture contains

50%

pentane (1),

30%

hexane (2) and

20%

cyclohexane (3) (all in\ mol-

%

), At

T=400K

, the pressure is gradually increased. What is the dew point pressure and the\ composition of the first liquid that is formed? Assume ideal liquid mixture and ideal gas (Raoult's\ law). Use the Antoine Equations for vapor Pressure.\

LOG_(10)(P_((bar ))^(sat ))=A-(B)/(T+C)
