Question
At 300K, the vapour pressure of an ideal solution containing 3 mole of A and 2 mole of B is 600 torr. At the same temperature if 1.5 mole of A and 0.5 mole of C (non-volatile) are added to this solution the vapour pressure of solution in creases by 30 torr. What is the value of p0B ?
Options
A.940
B.405
C.90
D.none of these
Solution
P = p0AxA + p0BxB
600 = p0A
3p0A + 2p0B = 3000
630 = p0A
4.5p0A + 2p0B = 4410
1.5p0A = 1410; p0A = 940 and p0B = 90
600 = p0A
3p0A + 2p0B = 3000
630 = p0A
4.5p0A + 2p0B = 4410
1.5p0A = 1410; p0A = 940 and p0B = 90
