Question

The reactions
C2H6. --> C2H4 + H2
C2H6 + H2 --> 2CH4
take place in a continuous reactor at steady state. The feed contains 85.0 mole % ethane (C2H6)
and the balance inerts (1). The fractional conversion of ethane is 0.501, and the fractional yield of
ethylene is 0.471. Calculate the molar composition of the product gas and the selectivity of ethylene
to methane production.​
