Catalysts in a reaction
Do catalysts always appear on the left side of the reaction initially and then move to the right in the second step of the reaction?

Re: Catalysts in a reaction
If the catalyst shows up in the reactant side, then it must show up again in the products side of the equation at some step (not necessarily only the second) because catalysts cannot be totally consumed by the reaction.

Re: Catalysts in a reaction
At some point in the reaction mechanism, the catalyst would show up on the left side as well because it is important that the enzyme cancels when you add up the elementary steps.

Re: Catalysts in a reaction
If the substance shows up in the products and isnt cancelled out later by a reactant, then it can not be an intermediate.

Re: Catalysts in a reaction
Intermediates are produced by one of the reaction steps, meaning it first appears as a product. It then acts as a reactant in subsequent steps, ensuring that it is cancelled out in the overall reaction.

Re: Catalysts in a reaction
Catalysts go from reactant to product, while intermediates go from product to reactant.

Yes! Intermediates are not in the overall reaction too; they are produced then consumed. Catalysts are consumed then produced.

Re: Catalysts in a reaction
Yes, catalysts always go from reactant to product and not the other way around

Re: Catalysts in a reaction
A catalyst will be present at the beginning of a reaction and at the end of the reaction. An intermediate on the other hand is present at the beginning but is eventually consumed by the end of the reaction. So yes, a catalyst will appear on the left side towards the beginning but shifts to the right at the end.
