Arrhenius

The Arrhenius equation describes how the rate of a chemical reaction depends on temperature. It states that as temperature increases, molecules move faster and are more likely to collide with enough energy to react. This relationship is governed by the activation energy—the minimum energy needed for the reaction to occur. The equation helps scientists predict how quickly reactions happen under different temperatures, which is important in fields like chemistry, engineering, and biology. In essence, higher temperatures generally speed up reactions, and the Arrhenius equation quantifies this effect mathematically.
