The production of 1,3-butadiene can be carried out by the dehydration of 1-butene.

c2h5ch: ch2(g) > h2c: chhc: ch2(g) + 2 h2(g)

side reactions are suppressed by the introduction of steam. if equilibrium is attained at 950k and 1 bar and if the reactor product contains 12-mol-%, 1,3-butadiene, find :

(a) the mole fractions of the other species in the product gas.

(b) the mole fraction of steam required in the feed.
