Using the outcome fo previous example, arrange benzene, 1,3-cyclohexadiene, and cyclohexene in the order of decreasing rate of monohydrogenation. Strategy: Since the change in the number of moles is the same for each hydrogentaion,we assume that the DeltaS's (entropy changes) are about the same, and that the Delta_(h)H's are directly related to the DeltaH's.

1.	Using the outcome fo previous example, arrange benzene, 1,3-cyclohexadiene, and cyclohexene in the order of decreasing rate of monohydrogenation. Strategy: Since the change in the number of moles is the same for each hydrogentaion,we assume that the DeltaS's (entropy changes) are about the same, and that the Delta_(h)H's are directly related to the DeltaH's.
Answer» Solution :The order of chlohexene `(-120 kJmol^(-1))gt1,3-`CYCLOHEXADIENE `(-112kJmol^(-1))GT` benzene `(+24kJmol^(-1))`
