How do catalysts increase reaction rate
WebJan 30, 2024 · The catalyst is another factor that can affect the rate of a reaction. Let's look at the balanced equation for the decomposition of hydrogen peroxide, which turns into water and oxygen. And let's … WebEnzymes are catalysts. They are usually proteins, though some RNA molecules act as enzymes too. Enzymes lower the activation energy of a reaction - that is the required amount of energy needed for a reaction to occur. They do this by binding to a substrate and holding it in a way that allows the reaction to happen more efficiently.

WebMay 25, 2024 · A catalyst is a substance that speeds up the rate of the reaction, without being consumed by the reaction itself. In the reaction of potassium chlorate breaking … Webthe reaction to take place. By lowering the activation energy, catalysts make it easier for the reactants to overcome the energy barrier and transform into products. The surface area of the reactants can also affect the rate of a reaction. If the reactants are in the form of solids, increasing the surface area by grinding them into a fine powder will increase the rate of …
WebA catalyst increases the rate of the reaction because: They provide an alternative energy pathway that has a lower activation energy This means that more particles have the activation energy required for the reaction to take place (compared to without the catalyst) and so the speed of the reaction increases
