For each question think carefully and select the ONE BEST statement of Collision Theory that tells how or why the change described affects the reaction rate. More of the right molecules react. The molecules collide more often. The molecules have enough energy to react. The molecules are in the right position.
Sodium ions are a product of the reaction.
Because they are present, the reaction slows down. The more sodium ions present, the slower the reaction should go. The forward reaction is very slow at the beginning compared to the reverse reaction. The reverse reaction is very slow at the beginning compared to the forward reaction. The sodium ions speed up the forward reaction because some of the product is already present to make it seem as if the forward reaction is already going on before it can really start.
