Chemical reactions are typically faster when a catalyst is added. This is because... 1. Molecules are moving faster when a catalyst is added, so it is easier to get over the activation barrier. This will increase reaction rate. 2. Molecules are moving faster when a catalyst is added, so the collisions occur with a higher energy which makes it easier to get over the activation barrier. This will increase reaction rate. 3. Adding a catalyst lowers the activation barrier, which makes it easier to get over the activation barrier. This will increase reaction rate. 4. None of these statements is correct.
