(1) For the system ethyl ethanoate (1)/ n-heptane (2) at 343.2 K,

In (7₁) = 0.95 x₂²

P₁ sat = 79.8 kPa

In (72) = 0.95 x₁²

P₂ = 40.5 kPa

a) Calculate the bubble point pressure at 343.2 K, x1 = 0.05.

b) Calculate the dew point pressure at 343.2 K, y₁ = 0.05.

c) Check whether an azeotrope exist, if yes, calculate the composition and P at this

condition.

d) Calculate 012. Which is more volatile component 1 or 2?

e) Calculate the dew point T at 100 kPa and y₂ = 0.7.
