Sunflower oil contains 0.080 mol palmitic acid (c16h32o2)/mol, 0.060 mol stearic acid (c18h36o2)/mol, 0.27 mol oleic acid (c18h34o2)/mol, and 0.59 mol linoleic acid (c18h32o2)/mol. to create margarine from sunflower oil, the liquid oleic and linoleic acids are hydrogenated in the presence of a metal catalyst to form solid stearic acid. at a margarine production facility, a stream of 335.0 mol sunflower oil/hr is fed into a reactor. the fresh hydrogen source available is a mixture containing 0.95 mol h2/mol and 0.050 mol n2/mol. (n2 is inert in this process.) to insure complete hydrogenation, the hydrogen gas mixture is introduced into the reactor in 65.0% excess. all reaction products leave the reactor and proceed to a separator where palmitic and stearic acids are separated from the hydrogen gas mixture. the hydrogen gas mixture is recycled to the fresh feed stream, and 140.0 mol gas/hr of this recycle stream is purged to prevent the buildup of nitrogen gas. what is the composition of the purge stream?
