The Arrhenius Theory

The Arrhenius Theory explains how temperature affects the speed of chemical reactions. It states that molecules need enough energy to react, called activation energy. When temperatures are higher, molecules move faster and collide more often with enough energy to react, increasing reaction rates. Conversely, at lower temperatures, fewer molecules have enough energy, and reactions proceed more slowly. The theory also uses an equation that relates reaction rate to temperature and activation energy, helping predict how changing temperature influences reaction speed. Overall, it highlights the key role of energy and temperature in chemical processes.
