Webactivation 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. In transition-state theory, the activation energy is the difference in energy content between atoms or molecules in an activated or transition-state … WebEnzymes and activation energy. A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called … WebWhat is activation energy in Arrhenius equation? Notice that when the Arrhenius equation is rearranged as above it is a linear equation with the form y = mx + b; y is ln(k), x is 1/T, and m is -E a /R. The activation energy for the reaction can be determined by finding the slope of the line. -E a /R = slope. E a = -R•slope. \\u0026ctiver windows
