Acetylene is hyrodgenated to form ethane. The feed to the reactor contains 1.30 mol H2/mol C2H2. The reaction proceeds to completion. a. Calculate the stoichiometric reactant ratio (mol H2 reacted/mol C2H2 reacted) and the yield ratio (mol C2Hs formed/mol H2 reacted). mol H2 reacted/mol C2H2 reacted 2 0.5 mol C2Hs formed/mol H2 reacted b. Determine the percentage by which acetylene is in excess. 53.85 % c. Calculate the mass feed rate of hydrogen (kg/s) required to produce 5.00 x 106 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. i 0.19 kg/s
