Ethanol can be converted into either ethylene or acetaldehyde, by the following pair of reactions: 

C₂ H₅ OH ↔ C₂ H₄ + H2 O 

C₂ H₅ OH ↔ CH₃ CHO + H₂ 

But ethylene and acetaldehyde can also be con verted into butadiene: 

C₂ H₄ + CH₃ CHO ↔ C₄ H₆ + H₂

A reactor initially contains 10 moles of pure ethanol. Assuming all three of these reactions—and no others—occur, find the equilibrium composition of the reactor for the following. 

A. The reactor is at T = 500 K and P = 1 bar. 

B. The reactor is at T = 1000 K and P = 1 bar. 

C. The reactor is at T = 500 K and P = 5 bar.
