Butadiene is prepared by the gas phase catalytic dehydrogenation of 1-butene: C4H8(g)C4H6(g)+H2(g) The reaction is carried out at 900K and 1 bar, and the reaction equilibrium constant is, K900K=0.242. (i) In order to suppress side reactions, the butane is diluted with steam before it passes into the reactor. Estimate the equilibrium composition of the reaction mixture for a feed consisting of 10 moles of steam and 1 mole of 1-butene. [8 marks] (ii) Find the extent of reaction if the inert (steam) was absent. [4 marks] (iii) Find the total pressure P that would be required to obtain the same conversion as in (i) if no inert (steam) was present. [3 marks]
