24. Liquids A and B form an ideal solution. At a certain temperature the total vapour pressure of a mixture of A and B is 400 mm. The mole fraction of A in the liquid mixture in equilibrium with the vapour phase is
0.4. If the vapour pressure ratio (P)/ P) for the pure liquids at this temperature is 1/6, what is the
partial pressure of A in the vapour phase?
(A) 50mm
(B) 60mm
(C) 70mm
(D) 40mm

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
