Which has the highest activation energy?

Answer 1

If the activation energy of a reaction is high, then it requires a large amount of energy to initiate the reaction. The situation arising when a spontaneous reaction has a large activation energy is similar to rolling a ball over a hill. At first, energy must be expended to move the ball to the crest of the hill (or, in the case of a reaction, impart enough energy to the molecules so that their bonds can be sufficiently weakened). However, once the ball is at the top of the hill, it rolls down on its own. This is analogous to the reforming of chemical bonds, which releases energy. High activation energies are typical when a reaction involves molecules whose bonds are strong.

Answer 2

A reaction with a higher activation energy requires more energy to initiate the reaction. In general, reactions involving the breaking of strong chemical bonds have higher activation energies compared to reactions involving weaker bonds.
