WebActivation energy is illustrated in the graph in Figure 3.9.4. Figure 3.9.4 Even though this reaction is exothermic, it requires “help” to get started. This “help” is the activation … WebActivation energy is the minimum energy required to start a chemical reaction. In chemical kinetics, the rate constant depends on the activation energy (via Arrhenius equation). If the activation energy is high, the reaction would be slow. If the activation energy is low, the reaction would be fast. WebDec 16, 2024 · This small amount of energy input necessary for all chemical reactions to occur is called the activation energy (or free energy of activation) and is abbreviated E A. Figure 6.2 D. 1: Activation energy: Activation energy is the energy required for a reaction to proceed; it is lower if the reaction is catalyzed. chicken and hummus bowl
