When the amount of substrates (reactants) increases, the reaction rate changes differently in catalyzed and non-catalyzed reactions. Describe this.
Generally, increasing the temperature increases the rate of a reaction. This is because: O increasing the temperature increases the frequency of collisions O increasing the temperature increases the average energy of the collisions and increases the frequency of collisions O increasing the temperature lowers the activation energy of the reaction increasing the temperature increases the average energy of the collisions.
