you can solve all if you want i just dont get part e

Solve all problems showing all necessary steps and assumptions (Table B.2 in APPENDIX B of the recommended textbook can be used for the calculation of Pisat) (1) For the system ethyl ethanoate (1)-heptane (2) at 343.2K, ln(1)=0.95x22P1sat=79.8kPaln(2)=0.95x12P2satt=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
