Final answer:

High activation energy makes a chemical reaction harder to start, causing slower reaction rates.


Explanation:

High activation energy in a chemical reaction has the effect of making the reaction harder to start because a higher activation energy barrier needs to be overcome for the reaction to proceed. This means that reactions with high activation energy levels tend to occur at slower rates compared to reactions with lower activation energy levels.
