Catalysts

Postby Christiana2D » Sat Mar 17, 2018 11:15 am

If catalysts aren't consumed during a reaction, why don't they show up in the overall balanced reaction such as the one in question 15.71?

Catalysts are not included in the overall balanced reaction because they are present in the beginning and regenerated at the end. If you think about it, the catalyst would cancel out. Also, catalysts participate in the reaction by lowering the activation energy, but they are not necessarily reactants or products.

Catalysts are used and then regenerated, so they appear on both sides of the equation. This means that when you do the overall balanced equation, they would appear on both sides, thus cancelling out.
