Please I want the answer of question C

(1) For the system ethyl ethanoate (1)/ n-heptane (2) at 343.2K, ln(1)=0.95x22P1sat=79.8kPaln(2)=0.95x12P2sat=40.5kPa a) Calculate the bubble point pressure at 343.2K,x1=0.05. b) Calculate the dew point pressure at 343.2K,y1=0.05. c) Check whether an azeotrope exist, if yes, calculate the composition and P at this condition. d) Calculate 12. Which is more volatile component 1 or 2 ? e) Calculate the dew point T at 100kPa and y2=0.7
