An equimolar solution of n-heptane and n-octane was subjected to Rayleigh distillation (single differential) at near atmospheric pressure with 60% of the liquid distilled. Use the table below, which indicates liquid-vapor equilibrium n-heptane compositions for the distilled mixture at the indicated pressure to answer the following items. a) Which of the components is the most volatile (without searching for more information, use only the information provided in the statement)? Can you chemically explain why? b) Calculate the distillate and residue concentrations
