Does increasing the amount of catalyst added to, say, a solution of Hydrogen Peroxide, make the rate of reaction go faster. Is the rate of reaction directly proportional to the amount of catalyst added to the solution? Or does the experiment go at the same rate regardless of how much catalyst there is? Thanks would really appreciate some answers. - Sarah
Catalyst do not participate in the reaction but it speeds up the reaction. If you increase the amount of catalyst from the required amount, it would somehow negates its positive response or it would result in producing another product.
Adding a catalyst would increase the rate of reaction. This could decrease the activation energy, the amount of kinetic energy needed for the reaction to occur. Hope that helps
A catalyst works by providing the optimal conditions for a reaction to occur, so the more there is, the more contact it has with the reactant/s, so the more there is, the faster the reaction will take place, until there is a point where there are too many catalyst sites for the number of reactant molecules, so it doesn't speed it up any further past that point, if it's a relatively slow reaction it may slow the process by diluting the solution too much with useless catalyst sites, but generally the reaction rate will reach a point where it will not become any faster, and stay at that maximum speed. less catalyst does mean less speed though, as the catalyst sites have more work to do. hope this helps.
