Question

Reactant A can participate in both of these reactions:

Answer 1

The activation energy is the amount of energy required to initiate a certain reaction. The activation energy may considered as an "energy barrier" that has to be overcome in order for a reaction to begin. If a reaction has a lower activation energy, then it will occur more easily and at a faster rate than a reaction with a higher activation energy. Therefore, the reason that reaction 1 is faster than reaction 2 is because it has a lower activation energy than reaction 2.

Answer 2

Answer:

Higher activation energies generally lead to lower reaction rates.  Reaction 2 has a lower reaction rate than Reaction 1.  The activation energy for Reaction 2 is probably higher than that for Reaction 1.
