3. Kindly answer this problem. Thank you.
4.39. Acetylene is hydrogenated to form ethane. The feed to the reactor contains 1.50 mol H2/mol C¿H2.
(a) Calculate the stoichiometric reactant ratio (mol H2 react/mol C¿H2 react) and the yield ratio
(kmol C2H6 formed/kmol H2 react).
(b) Determine the limiting reactant and calculate the percentage by which the other reactant is in
excess.
(c) Calculate the mass feed rate of hydrogen (kg/s) required to produce 4x 10° metric tons of ethane
per year, assuming that the reaction goes to completion and that the process operates for 24
hours a day, 300 days a year.
