Lecture 9 Catalysts and Reaction Rates

Flashcards covering catalysts, enzymes, and reaction rates from the lecture notes.

Catalyst

Chemical species that increases the rate of a reaction

Catalyst

It is introduced at the beginning of a reaction and regenerated at the end

Catalyst

Lowers the activation energy of the reaction by changing the mechanism of the reaction

Homogeneous Catalyst

Is in the same phase/physical state as the reactants

Heterogeneous Catalyst

Is in a different phase than the reactants

Catalyst

Speeds up a chemical reaction by lowering the activation energy

Enzyme

Biological catalyst that greatly increases the rate of a specific biochemical reaction

Substrate

Biochemical molecule that binds to the active site of an enzyme to form an enzyme-substrate complex
