Question

Benzene is one of the compounds used as octane enhancers in unleaded gasoline. It is manufactured by the catalytic conversion of acetylene to benzene.
$2C_2{H}_2\to C_6{H}_6$
Would this reaction be most useful commercially if k were about 0.01, about I, or about 10 ? Explain.

Answer 1

If rate constant is greater than 1 then it will be spontaneous and will require no catalyst so commercially more feasible.

So this reaction is commercially more useful if K=10.
