THArrhenius Equation ✍️
It explains how temperature speeds up chemical reactions by revealing the hidden energy barrier that molecules must cross before they can transform. In any substance, molecules are constantly moving and colliding, but most collisions are too weak or poorly timed to cause change. Only particles with enough energy can overcome the activation barrier and rearrange into products. At lower temperatures, very few molecules have this required push, so reactions proceed slowly. As temperature rises, molecular motion becomes more intense, and a much larger fraction of particles gain the needed energy. This causes successful collisions to happen far more often. The result is a rapid increase in reaction rate, often dramatic even with a small temperature change. Scientists use this relationship as a precise tool to predict reaction speeds, estimate activation energy, and control processes in chemistry, biology, and industry.
