Styrene (C3H3) is produced by the dehydrogenation of ethylbenzene (C3H10) in the presence of steam at 600°C and 2.00 atm. Consider a tubular reactor operating with 15:1 steam to ethylbenzene feed ratio at the reactor entrance. At this temperature, the reaction has an equilibrium constant K, = 2.00 atm (K, is the equilibrium constant based on partial pressures. For component a, the partial pressure is defined as Pa = y.P, where P is the operating pressure of the reactor and y. is the mole fraction of component a. The chemical reaction is as follows:

Question
Styrene (C3Hs) is produced by the dehydrogenation of ethylbenzene (C3H10) in the presence of steam at
600°C and 2.00 atm. Consider a tubular reactor operating with 15:1 steam to ethylbenzene feed ratio at the
reactor entrance. At this temperature, the reaction has an equilibrium constant K, = 2.00 atm (K, is the
equilibrium constant based on partial pressures. For component a, the partial pressure is defined as
Pa = yaP, where P is the operating pressure of the reactor and ya is the mole fraction of component a. The
chemical reaction is as follows:
C3H10 E→ C3H8 +H2
Determine the fractional conversion of the ethylbenzene to styrene at equilibrium.
