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.
When atoms aren't close together.
Which has the highest activation e {a}
activation energy ( I know it is right because it is in my science book)
Enzymes are catalysts, they reduce the activation energy.
Activation energy is the amount of energy needed to start a reaction.
This energy is called "energy of activation", it is used to overcame the energy barrier between reactants and products.
The energy needed to statr a chemical reaction is the 'Activation Energy' , which is given the symbol (Ea).

An exergonic reaction is activation energy (or energy of activation). An endergonic reaction is essentially the opposite of an exergonic reaction.
Activation energy is the amount of energy that should be gained by potential reactants, for a reaction to occur. A reaction can be occurred by reducing the activation energy of the reaction or increasing the activation energy of the reactants. Activation energy should be added.
activation energy activation energy
That is called the activation energy or energy of activation (Ea).
Enzymes are catalysts, they reduce the activation energy.
Activation energy is the amount of energy needed to start a reaction.
This energy is called "energy of activation", it is used to overcame the energy barrier between reactants and products.
The energy needed to get a reaction started is called activation energy.
Activation energy is the energy required by a reaction for the reaction to occur. The catalyst lowers the activation energy, making it easier for the reaction to happen.Improvement:A catalyst don't lowers the activation energy. A catalyst creates a alternative route (*) for the same reaction with a lower activation energy.* = as a result of the interaction of the reagents with the catalyst.
Activation energy describes the energy that is required to get chemical reactions started.
