3 For the system n-pentane (1)-heptane (2), the vapor pressures of the pure components are given by the following Antoine equations, where P1SAT[kPa] and T[C] lnP1SAT=13.8183[2,477.07/(T+233.21)]lnP2SAT=13.8587[2,911.32/(T+216.64)] Assuming that Raoult's Law applies for the system, calculate the following: 1.1 Liquid and vapor compositions at 70C and 100kPa 1.2 Temperature and vapor composition at 100kPa and x1=0.4 1.3 Find the equilibrium pressure and vapor composition at 50C and x2=0.6 1.4 Calculate k1 and k2 at x1=0.5 and 70C. What could you conclude from the results? 1.5 Find the relative volatility at x1=0.4 and 50C. Plot a graph y1 versus x1 1.6 Based on the previous results, do you think that this system easy to separate
