Introduction to Activation Energy Activation energy is a fundamental concept in chemistry that plays a critical role in understanding how chemical reactions occur. At its core, activation energy (often denoted as Ea) is defined as the minimum amount of energy required for reactants to undergo a transformation into products. This energy barrier must be overcome for a reaction to take place, which is a key factor in determining reaction rates. To grasp the importance of activation energy , it's ... Activation Energy - Activation energy can be defined as the minimum amount of energy required to initiate a chemical reaction. It acts as a barrier that reactant molecules must overcome to transition into product molecules. Activation energy is the minimum energy barrier that reactant molecules must overcome to transform into products . A reaction occurs only if enough molecules have kinetic energy equal to or greater than this barrier, which usually requires sufficiently high temperature. activation energy , in chemistry, the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport.
