Determine the temperature first bubble created from a saturated liquid mixture of benzene and toluene containing 45 mole percent benzene at 200 kPa. Benzene and toluene mixtures may be considered as ideal.

Also, determine the composition of toluene in the vapor phase for first bubble created from a saturated liquid mixture of benzene and toluene containing 45 mole percent benzene at 200 kPa. Benzene and toluene mixtures may be considered as ideal.
