Your answer is asked on a too broad spectrum.
A brief explanation:
A chemical reaction is a reaction where certain molecules are reformed to other molecules.
To split Water (H2O) into H2 and O2, it needs to be heated to 1800 C, requiring approximately 7524 Kj.
However; Sodium (Na) is an alkaline metal, which produces a chemical reaction when it merely touches air or water.
PS: Water is more often split with electrolyse (with electricity) than with thermolyse
The general sort of energy required is the activation energy. Which can be all kinds of energy.
kinetic energy from collisions between particles.
Activation energy is needed to get a chemical reaction going.
... is called "activation energy".
Activation Energy.
You need to get the reaction above its activation energy before it will start.
What term refers to the amount of energy needed to begin a chemical reaction
This is true. Energy is required to begin all reactions.
The activation energy, once put in force, will be affected by the density, static, and kinectic energy of an object, but will still have a direct impact on the energy of reaction that is yielded from the initial force.
There are several sources of energy that could provide the activation energy needed for a chemical reaction to take place. Usually it is thermal energy, but photoexcitation (excitement by light energy) and electrochemical activation (excitement by electricity) are also commonly used.
This is the activation energy.
Any catalyst will make a chemical reaction easier or quicker to happen by lowering the activation energy. On a energy diagram, you will see a lower "hill" for activation energy, which corresponds to less energy required to begin the reaction.
Activation energy is the least amount of energy needed to start a chemical reaction. It is used to activate atoms or molecules in order for them to begin a chemical reaction.
A chemical reaction begin only if the activation energy has a specific value.
Catalysts decrease activation energy.
You need to get the reaction above its activation energy before it will start.
What term refers to the amount of energy needed to begin a chemical reaction
Catalysts greatly reduce the amount of activation energy needed to begin a reaction.
This is true. Energy is required to begin all reactions.
The activation energy, once put in force, will be affected by the density, static, and kinectic energy of an object, but will still have a direct impact on the energy of reaction that is yielded from the initial force.

High Energy produced with high velocity which required for nuclear reaction
