In 1894 he gave the first modern definition of a catalyst and turned his attention to catalytic reactions.

Even subtle changes in these parameters can significantly influence the selectivity and rate of catalytic reactions.

According to our calculations, the catalytic reaction and phase change should have begun instantaneously.

Hot atoms are expected to play important roles in catalytic reactions.

"It was too big an explosion to be either a chemical or catalytic reaction," she said.

Moreover, when speaking about catalytic reactions, the diffusion may also limit the reaction.

Because of this preactivation step, many catalytic reactions involve an induction period.

More often, the support and the catalyst interact, affecting the catalytic reaction.

The support may be inert or participate in the catalytic reactions.

After the catalytic reaction, the product is then passed on to another enzyme.
