If benzene. Toluene and para-xylene are mixed in molar ratio 1:2:3. Then answer the following question carefully. Estimate the dew point pressure (At the dew point pressure all liquid vaporiaed ) for the above mixture (approximately)

Answer»

180 torr
152 torr
138 torr
156 torr

Solution :At the DEW pointpressure all LIQUID vaporized
`(1)/(P_(("dew point")))=[(Y_(B))/(P_(B)^(@))+(y_(T))/(P_(T)^(@))+(Y_(X))/(P_(X)^(@))]"" (Y_(B)=(1)/(6), Y_(T)=(2)/(6), Y_(X)=(3)/(6))`
