What effect does a catalyst have on energy?
What will be an ideal response?
A catalyst lowers the energy needed for a reaction to occur (if energy is needed, that is) but is not used up in the reaction. A catalyzed reaction is one that would not occur spontaneously without a catalyst but that will occur with the assistance of a catalyst. When the reaction is over, the amount of catalyst present remains the same.
