The two liquids A and B have the same molecular weight and form an ideal solution. The solution has the vapour pressure 700 mmHg at `80^@C` . The above solution is distilled without reflux till 3/4 of the solution is collected as condensate. The composition of the condensate is `x'_A=0.75 ` and that of the residue is `x_A` = 0.3. If the vapour pressure of the residue at `80^@C` is 600 mmHg, calculate`x_A, P_A^@` and `P_B^@`
