Webcatalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions. Most solid catalysts are metals or the oxides, sulfides, and halides of metallic elements and of the semimetallic elements boron, aluminum, and silicon. … WebActivation energy is the minimum amount of total energy required to for a reaction to occur. The amount of energy required is dependent on whether a reaction is endothermic or exothermic. An endothermic reaction is any reaction that requires an addition of energy to occur. It is a net absorption of heat.
WebActivation Energy is the energy which must be provided to potential reactants. Moreover, in a chemical or a nuclear system so that a spark can be given to a chemical reaction or a nuclear reaction.
