Explain the molar fraction of benzene in the liquid phase

Reference no: EM13503980

One mole of benzene (component 1) is mixed with 2 moles of toluene ( component 2) at 60 C and at such low pressure that everything is in the vapor phase. At 60 C vapor pressures of benzene and toluene are po1=51.3 kPa and po2= 18.5 kPa. Assume ideal solution behavior

a) when the pressure of the system increased, at what pressure pfd will the first drop form?

b) what is the molar fraction x1fd of benzene in the first drop of liquid?

c) Further increase of the pressure eventually leads to a last (very small) bubble of vapor in equilibrium with the liquid phase. What is the molar fraction y1lb of benzene in the last bubble?

d) What are the values of (i) the pressure, (ii) the molar fraction of benzene in the liquid phase, and (iii) the molar fraction of benzene in the vapor phase when 1/4 the initial vapor phase has condensed?
