Isopropanol can dehydrate to either propylene or diisopropyl ether over the temperature range: 25 - 300C and 1 bar total pressure. Analysis of the reaction system detects isopropanol, diisopropyl ether, water, and propylene. a) Identify a set of independent reactions to describe this system. b) With a basis feed of 1 mol isopropanol to an isothermal reactor, solve your system of reactions and plot the reaction progress (extent) variables and compositions over the temperature range: 25C to 300C, assuming that the system reaches equilibrium at the reactor exit. c) Repeat (b.) but now including an inert gas (nitrogen) in the reactor feed, such that the feed contains only 10 mol % ethanol. Explain how reaction progress and product composition is affected by this addition of inert gas.
