Answer:
[tex]\boxed{\text{True; False; True}}[/tex]
Explanation:
Catalysts lower activation energy. TRUE.
They provide an alternate pathway with a lower activation energy.
Catalysts are consumed by the overall reaction. FALSE.
They take part in the reaction, but they can be recovered unchanged at the end.
Catalysts speed up the chemical reactions. TRUE.
If the activation energy is lowered, a greater percentage of the molecules will have enough energy to get over the energy barrier.
Its like lowering the high-bar in a track and field meet. The lower the bar, the more athletes will be able to get over it.
