In homogeneous catalysis, catalysts are in the same phase as the reactants. Chemistry is traditionally divided into organic and inorganic chemistry. Computed Properties of C7H9N, Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In an article，Which mentioned a new discovery about 108-47-4
Dimethylpyridines undergo deuterium-hydrogen exchange when heated in deuterium oxide containing potassium carbonate at ring positions 2 and 6 when these positions are unsubstituted and at methyl groups located at ring positions 2,4, and 6 exclusively.
Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amountComputed Properties of C7H9N, you can also check out more blogs about108-47-4
