Consider the reaction pathway graph below.

which statement describes how this graph would change if the reaction could be made to go faster?
the hill would be taller.
the hill would be shorter.
c would be higher than a + b.
c would be equal with a + b.

Hello!

If the reaction could be made to go faster B. The hill would be shorter.

The "hill" is called Activation Energy. It is the energy of the activated intermediate compound needed to complete the reaction. Catalysts are substances that don't intervene in the reaction which speed up the rate of a given reaction by lowering the Activation Energy giving alternate reaction pathways with lower-energy intermediates. If the reaction could be made to go faster with the use of a catalyst, then the Activation Energy would be lower and the "hill" would be shorter.

Have a nice day!
