Which of the following would describe a substance acting as a catalyst? Vinegar is diluted and the rate of the reaction with baking soda decreases. This is because the more room you give the vinegar molecules, the faster they can move and collide with the baking soda. Manganese (IV) oxide is added to peroxide and the peroxide decomposes at a faster rate. The manganese (IV) oxide is not used up in the reaction and can be used again. More baking soda is added to vinegar and the rate of bubbling increases. This is because the activated complex is dependent on the baking soda to vinegar molar ratio. Heat is added and the reaction rate increases. The heat is acting as a catalyst because it lowers the activation energy.
