The relationship between temperature and reaction rate in chemical reactions is described by the Arrhenius equation. According to this equation, the reaction rate increases with an increase in temperature. This is because temperature affects the kinetic energy of the reactant molecules. As the temperature rises, the molecules gain more energy, and their kinetic energy increases. This higher kinetic energy leads to a higher frequency of successful collisions between reactant molecules, which results in an increased reaction rate. The Arrhenius equation also shows that an increase in temperature leads to an exponential increase in the reaction rate, as temperature is present in the exponent of the equation. Overall, higher temperatures generally lead to faster reactions, while lower temperatures slow down reaction rates.
