The vapour pressure of ethyl acetate is 118.3 mmHg at 29.5°C and 760mmHg at 77°C. a) Estimate the vapour pressure of ethyl acetate at 45°C. (hints: use Clausius-Clapeyron equation) b) A gas mixture contains 90% nitrogen and 10% ethyl acetate by mole under the pressure of 2 atm and temperature of 80°C. Is this gas nitrogen saturated by ethyl acetate or not, what is the dew point? c) If 100 mol such a gas mixture (as described in b) flows through a condenser under constant pressure 2 atm and is cooled to 29.5°C, how much ethyl acetate will be condensed?
