WebApr 11, 2024 · Well, the activation energy is the extra energy given to get useful work done. In chemistry, we call it the minimum amount of energy (or threshold energy) needed to activate or energize molecules or atoms to undergo a chemical reaction or transformation. The activation energy units are LCal/mo, KJ/mol, and J/mol. WebDec 11, 2024 · Catalysts do not lower the activation energy or increase the kinetic energy, as I've just learned trying to figure out this question, but they provide an alternative activation energy, lower than the initial one, that, if met, will allow the reaction to take place.

WebCatalysts affect the rate of a chemical reaction by altering its mechanism to provide a lower activation energy. Catalysts can be homogenous (in the same phase as the reactants) or heterogeneous (a different phase than the reactants). ...
