1. A process for the oxidative dehydrogenation of ethane comprising contacting a feed stream comprising ethane, oxygen, and acetic acid with an oxidative dehydrogenation catalyst under oxidative dehydrogenation conditions in an oxidative dehydrogenation reactor to produce a product stream comprising ethylene, unreacted ethane, water, and acetic acid, wherein the concentration of acetic acid in the feed stream is from 0.5 to 10 vol % of the feed stream.
