Answer:
1)Molecules must collide at a high enough energy to break bonds.
2)the minimum amount of energy required to break bonds and start a chemical reaction
3)Which change can encourage a reaction? adding heat
4)More energy is released when forming the bonds of the products because a lot of heat is given off, which indicates energy was released.
5)Two H–H bonds are broken, one O=O bond is broken, and four H–O bonds are formed.
The phrase best describes activation energy is that it is the minimum amount of energy required to break bonds and start a chemical reaction.
The word activation energy, in chemistry is known to be the little or minimum amount of energy that is needed by one to be able to ignite or activate atoms or molecules.
The molecules or atoms are activated to a condition where they can be said to undergo chemical transformation or a kind of physical transport.
