Ethane (C2H6) can be dehydrogenated to ethylene (C2H4), which can be dehydrogenated further to acetylene (C2H2). A reactor is fed with ethane and steam at a 1:1 mole ratio (The steam simply acts as a diluent). If the reactor runs at 1 atm and the reactions reach equilibrium, find the fractional yield and selectivity for ethylene at 800 K and 1200 K. Choose a basis of 100 gmol/h for ethane fed to the reactor.
