Abinary mixture of acetonitrile (1) and nitromethane (2) is assumed to be an ideal mixture. if the overall composition is 60% (1), calculate the following:

i) bubble point pressure and corresponding vapor phase composition at 75oc.

ii) dew point pressure and corresponding liquid phase composition at 75oc.

iii) bubble point temperature and corresponding vapor phase composition at 1 atm.

iv) dew point temperature and corresponding liquid phase composition at 1 atm.

given: ln p1v = 14.27 - 2945.5/(t+224) and ln p2v = 14.2 - 2972.6/(t+206), where t is in oc and p is kpa
