Mixture of volatile components A and B has total vapour pressure (in torr) P = 254 - 119 X A where, X A is mole fraction of A in mixture. Hence, P A o and P B o are (in torr)

Question

Mixture of volatile components A and B has total vapour pressure (in torr) P = 254 - 119 X A where, X A is mole fraction of A in mixture. Hence, P A o and P B o are (in torr), 254, 119, 119, 254, 135, 254, 154, 119

MARKS App · Accepted Answer

When X A = 1 , P = P A o So P A o = 254 - 119 = 135 t o r r When X A = 0 , P = P B o So P B o = 254 torr.
