Styrene is produced from ethylbenzene in a gas - phase reaction. The true equilibrium constant at 9 0 0 K is 0 . 3 6

Styrene is produced from ethylbenzene in a gas-phase reaction.
The true equilibrium constant at 900K is 0.36 :
Ethylbenzene C8H10(g)> Styrene C8H8(g)+H2(g)
(a) The reaction is carried out in an isobaric isothermal continuous flow reactor (open system, steady-state) at 1 bar and 900K. Pure ethylbenzene is fed into the reactor. What maximum conversion can be achieved? 20 points
(b) Steam is co-fed into the reactor from problem (a) along with ethylbenzene at a 9:1 molar ratio (9 moles of steam are added per 1 mole of ethylbenzene). Find the maximum conversion and molar composition of the gas mixture at equilibrium. 30 points
(c) Now the reaction is carried out in an isothermal constant-volume batch reactor (closed system) at 900K. Note that the reactor is not isobaric anymore. The initial pressure is 1bar. Pure ethylbenzene is loaded into the reactor. Find maximum conversion and pressure in the reactor at equilibrium. 50 points
