What factors affect the rate of catalase catalyzed reactions?

Answer 1

If your question is "What affects catalyst performance?" (i.e. what stops them from working) then there are 2 main things:

Atoms permanently bonded to the surface, blocking it, and so that stops other reactant molecules from sticking to it (catalyst poisoning)

Catalyst sintering: This can be seen on high temperature solid metal catalysts, where there is a gradual loss of surface area for reactant molecules to stick to as a result of the individual catalyst surface atoms combining together (due to the heat) to make one big blob of lower surface area

Answer 2

The function of a catalyst is to speed up the rate of a reaction. The factors that affect how a catalyst works include temperature, nature of the substrate and pH.

Answer 3

concentration of reactants, temperature, medium in which the reactions occur, salinity, pH, and presence of catalysts and competitors.

Answer 4

The surface area of reactants and light also may affect the rate of a reaction.
