WebCatalysts increase the rate of reactions. Heterogeneous catalysts are in a different phase from the reactants. Controlling the ways catalysts work is essential to their use. Sequence … WebMar 9, 2024 · A catalyst increases the rate of a reaction by decreasing the activation energy providing an alternative pathway of reduced activation energy making it easier for products to be formed. The need for adding catalysts is to reduce the activation energy which prevents or delays the reaction from occurring.

How does a catalyst increase the rate of a reaction? - Brainly

WebFeb 12, 2024 · The reason for this is because the reactants are decreasing as a function of time, the rate would come out to be negative (because it is the reverse rate). Therefore, putting a negative sign in front of the variable will allow for the solution to be a positive rate. Chemical reactions vary greatly in the speed at which they occur.
