Question

when 1 mole of benzene is mixed with 1 mole of toluene

Answer 1

Answer:

When 1 mole of benzene is mixed with 1 mole of toluene The vapour will contain: (Given : vapour of benzene = 12.8kPa and vapour pressure of toluene = 3.85 kPa).

Answer 2

vapor pressure of benzene will be more than toluene even when equal number of moles are taken

Explanation:

• we know that,

     Vapor pressure of benzene is 12.8 k Pa

     Vapor pressure of toluene is  3.85 k Pa

• As the vapor pressure of benzene is higher than the vapor pressure of toluene, benzene would be more volatile.

• Even when same moles of benzene and toluene is taken, since the vapor pressure differs at large scales, benzene will be more volatile.

    vapor will be more in benzene than toluene.
