Please I want the answer of question Cplease give correct answer

(I) For the system ethyl ethanoate (1)/ n-heptane (2) at 343.2 K, 111(71): 0.95 X22 In (72) = 0.95 x8 P1\" = 79.8 kPa P2\" = 40.5 kPa a) Calculate the bubble point pressure at 343.2 K, x. = 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. (I) Calculate 1112. Which is more volatile component 1 or 2'? e) Calculate the dew point T at 100 kPa and ya = 0.7
