Sample Problem

How does activation energy affect reaction rates? Choose all that apply.

The higher the activation energy, the slower the forward reaction will proceed

The higher the activation energy, the faster the forward reaction will proceed

The lower the activation energy, the slower the forward reaction will proceed

The lower the activation energy, the faster the forward reaction will proceed

Reaction rate is independent of activation energy

Solution

By raising the activation energy, fewer particles will have the necessary energy for the reaction to occur so the reaction proceeds slower.
