Q1

Liquids A and B form an ideal solution in the entire composition range. At 350 K , the vapor pressures of pure A and pure B are \(7\times {10}^{3}\mathrm{Pa}\mathrm{and}12\times {10}^{3}\mathrm{Pa}\), respectively. The composition of the vapour is in equilibrium with a solution containing 40 mole percent of at this temperature is:

a

\({\mathrm{x}}_{\mathrm{A}}=0.37;{\mathrm{x}}_{\mathrm{B}}=0.63\)

b

\({\mathrm{x}}_{\mathrm{A}}=0.28;{\mathrm{x}}_{\mathrm{B}}=0.72\)

c

\({\mathrm{x}}_{\mathrm{A}}=0.4;{\mathrm{x}}_{\mathrm{B}}=0.6\)

d

\({\mathrm{x}}_{\mathrm{A}}=0.76;{\mathrm{x}}_{\mathrm{B}}=0.24\)
