Question 1: Butene is obtained as a result of the dimerization reaction of ethylene: 2C₂H₄(g) C₄H₈(g). Ethylene/Nitrogen mixture is fed to a reactor at 150C. Ethylene/Nitrogen mole ratio is 0.5. If the products leave the reactor at 300C in the reaction with 75% conversion of ethylene, what is the heat of reaction? -- -- -- -- -- -- -- -- -- --

Question 2: Dehydration of ethyl alcohol to ethylene occurs by the following reaction: C₂H₅OH C₂H₄ + H₂O. In an adiabatic reactor, 2 moles of ethyl alcohol vapor enters at 200C and is transformed by 50%. What is the temperature of the products at the reactor outlet?

i will be happy if you can solve them clearly and ASAP!! i will give you thumbs-up
