Solve any question of Chemical Kinetics with:-. Patterns of problems. >. WebCatalysis (/ k ə ˈ t æ l ə s ɪ s /) is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (/ ˈ k æ t əl ɪ s t /).Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and …
WebRate equations take the form: k is the rate constant. This is the value that tells us how fast or slow a reaction is. Since the rate of reaction can be affected by a range of variables such as temperature or reactant concentration, the rate constant will also vary.
