Example 4

medium
A catalyst is added to a reaction and the reaction finishes faster. What changes, and what does not change about the reaction?

Solution

  1. 1
    The reaction rate changes because the catalyst lowers the activation energy and provides an easier pathway.
  2. 2
    The catalyst does not change the reactants, products, or the overall energy difference between them, and it is not used up permanently.

Answer

The reaction gets faster, but the final products and overall energy change stay the same.
Catalysts affect kinetics, not the identity of the substances involved. They make successful collisions easier without changing the reaction's starting point or ending point.

About Catalyst

A substance that increases the rate of a chemical reaction by providing an alternative pathway with lower activation energy, without being permanently consumed or chemically.
