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 factors that affect the rate of catalase-catalyzed reactions include concentration of substrate (hydrogen peroxide), concentration of catalase enzyme, pH, temperature, and presence of inhibitors or activators. These factors can influence the efficiency and speed at which catalase breaks down hydrogen peroxide into water and oxygen.

Answer 3

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 4

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

Answer 5

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