Identify the two important classes of catalysts. Analyze the chemical reactions that take place when a biological catalyst combines with a reactant (substrate) to form an unstable intermediate.© BrainMass Inc. brainmass.com December 15, 2020, 5:04 pm ad1c9bdddf
The two most important classes of catalyst are:
Heterogeneous catalysts: Here the catalyst is in a different phase (i.e. solid, liquid and gas) to the reactants. Heterogeneous catalysts provide a surface on which the reaction can take place.
In 175 words, this solution covers the two most important classes of catalyst, as well as the kinds of chemical reactions that occur when a biological catalyst combines with a reactant.
