Describe the different types of catalysts
WebCatalysts and activation energy. To increase the rate of a reaction you need to increase the number of successful collisions. One possible way of doing this is to provide an alternative way for the reaction to happen which has a lower activation energy. In other words, to move the activation energy on the graph like this: WebEnzymes and activation energy. A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called …

Lisa Lynn, 42, … WebEnzymes are the catalysts involved in biological chemical reactions. They are the “gnomes” inside each one of us that take molecules like nucleotides and align them together to create DNA, or amino acids to make proteins, to name two of thousands of such functions.
WebCatalysts can be divided into two types: homogeneous and heterogeneous. Homogeneous catalysts occupy the same phase as the reaction mixture, while heterogeneous catalysts occupy a different phase. Homogeneous catalysts allow for greater interaction with the reaction mixture than heterogeneous catalysts. Terms WebTypes of catalysts The catalysts have been divided into different types according to their behaviour and pattern of action. 1. Positive catalyst 2. Negative Catalyst 3. Auto catalyst 4.
