Activation energy is just the energy needed to start a reaction, so it is not clear which has the lowest. Some reactions have negative reaction energy, which is just equivalent to a barrierless reaction.

What is the minimum amount of energy needed to start a chemical reaction?
activation energy ( I know it is right because it is in my science book)
Why is the activation energy of an endothermic reaction is at least as large as its enthalpy?
In an endothermic reaction the energy of the products is higher than the energy of the reactants. The activation energy also is an energy increase. The activation energy must be at least as high as the products energy or the reaction would never take place. Thus, the activation energy must be at least as large as the enthalpy in an endothermic reaction.
Energy required to start chemical reaction?
Energy required for a reaction can vary. Depending on the atom it changes. The element will be more reactive if it has a low 1st ionization energy since it requires less energy to react. The most reactive element in Francium since it has the lowest 1st ionization energy level. If an element has a high electro-negativity then it will also be able to react with little energy.
What does an enzyme do to the activation energy needed to start a chemical reaction?
Enzymes are catalysts, they reduce the activation energy.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.

What is it called when energy is required to start a chemical reaction?
An exergonic reaction is activation energy (or energy of activation). An endergonic reaction is essentially the opposite of an exergonic reaction.
What would an enzyme do in a cell?
it lowers activation energy.
Why is the activation energy of an endothermic reaction is at least as large as its enthalpy?
In an endothermic reaction the energy of the products is higher than the energy of the reactants. The activation energy also is an energy increase. The activation energy must be at least as high as the products energy or the reaction would never take place. Thus, the activation energy must be at least as large as the enthalpy in an endothermic reaction.
What kind of energy do enzymes reduce?
activation energy activation energy
Is activation energy added or just there?
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.

Does endothermic have high or low activation energy?
An endothermic reaction would not necessarily have either a high or low activation energy; it could be either and would depend on the reactants. Also, the activation energy alone does not determine if a reaction is endothermic or exothermic; a low or high activation energy could be part of an endothermic or exothermic reaction, again depending on the reactants.

What is the minimum energy required for molecules to react with each other called?
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.
