摘要：

An analysis has been made of the compensation effect observed for literature data on ethane hydrogenolysis over ruthenium catalysts. Using a previously derived expression for the isokinetic temperature it is concluded that the rate determining step is the breaking of the Ru-C bond. This is in accordance with recent views of Sinfelt. In order to substantiate this conclusion a recently published kinetics investigation is reconsidered. The results show two mechanisms, one for ethane/hydrogen pressures < 2, the other one for ethane/hydrogen pressures > 3. In both cases the rate determining step seems to be the Ru-C bond breaking.
