Benzene C6H6 can be produce by the dehhdrogenation of cayclohexane C6H12 gas. The reaction has a hight acitivation energy (880 KJ mol ), is also endeothermic and reversible
C6H12 (g) + 120KJ <===> C6H6 (g) + 3H2(g)

1) Under what condition will the rate of the forward reaction be greatest?

2) for a mixture of all three gases at equilibrium in a sealed container, what condition will produce the maximum yield of benzene?

3) suggest conditions that would be used for the commercial production of benzene using this process. Explain why you chose these condition

This sure sounds like homework. Give us your attempts at an answer and we will be happy to expand on it and give you help to get it finished.
I would suggest that you treat parts 1 & 3 as related questions and part 2 as a stand alone question.

Yield is affected by K values (etc) and temperature (depends whether the reaction is endothermic or exothermic).

Rate is affected by catalyst, activation energy and temperature at which the reaction is performed.

Can you try your questions now?
