Question

1. How would the series of figures change in the presence of a catalyst?

Answer 1

No, it won't change the amount of reactants nor the products as a catalyst will only provide an alternative path where lower activation energy is needed for the process to take place.

hope this explains it

If it does, please give it a brainliest :)))

Answer 2

Answer:

The figures represent a time sequence for a chemical reaction.

1. The presence of a catalyst would add new molecules, catalyst molecules, to the figures. Catalysts are not consumed as the reaction takes place, so its molecules would remain the same in all figures.

On the other hand, a catalyst speeds up a chemical reaction, so the quantity of reactant and product molecules would also change, with greater amounts of products and lower of reactants.

2. Yes, it would. As stated before, the presence of a catalyst would increase the amounts of products and decrease the amounts of reactants.
