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.
Which of the following statements is false. Catalysts make a reaction rate go faster by providing a different route for the same reaction to proceed that requires less input energy. Increasing the concentration increases the rate of a reaction because more molecules are available in the same amount of space leading to more collisions with the correct orientation. Adding energy increases the rate of a reaction because more collisions happen with enough energy to break the bonds. Increasing the pressure by adding an inert gas increases the rate of reaction by causing more collisions.
