positive catalysts may either: (1) Reduce the activation energy required for the reactant particles to become an activated complex. (2) Force the particles to attain multiple or altered 'transition states' in such a way that the reaction takes place faster or with less energy. BTW, positive catalyst is a term for a catalyst that speeds up a ...
Learn what positive catalysts are and how they increase the rate of chemical reactions by providing an alternate path with less activation energy. See examples of positive catalysts such as enzymes, potassium permanganate, platinum and iron.
- What is the impact of positive catalysts?Answer : The impact of a positive catalyst on the chemical reaction is that a positive catalyst improves the ... Read full
- What is the effect of a positive catalyst on the activation energy?Answer : For the completion of any reaction, activation is required by the product. So, the amount of activat... Read full

Sep 21, 2022 · Learn what a catalyst is and how it speeds up a chemical reaction without being consumed by it. Find out the difference between positive and negative catalysts, and the units for measuring catalysis.
Nov 13, 2022 · The most effective catalyst of all is the enzyme catalase, present in blood and intracellular fluids; adding a drop of blood to a solution of 30% hydrogen peroxide induces a vigorous reaction. Rapid liberation of O 2 can result in a spectacular bubble bath if some soap is added.
Jun 30, 2023 · This page explains how adding a catalyst affects the rate of a reaction. It assumes familiarity with basic concepts in the collision theory of reaction rates, and with the Maxwell-Boltzmann distribution of molecular energies in a gas.
Jun 30, 2023 · This page looks at the the different types of catalyst (heterogeneous and homogeneous) with examples of each kind, and explanations of how they work. You will also find a description of one example of autocatalysis - a reaction which is catalysed by one of its products.
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the reaction. A catalyst works by providing a different pathway for the reaction, one that has a lower activation energy than the uncatalyzed pathway.
