Chemical Reactions
Endothermic Reactions
Endothermic reactions store energy and result in a decrease of thermal energy. Endothermic reactions result in the forming of bonds with less energy than it took to break them.

-
Exothermic Reactions
Exothermic reactions give off heat, making an increase in thermal energy, it also makes new bonds. Exothermic reactions result in the new bonds formed release more energy than it took to break the old bonds.
-
Energy Level
-
More energy is given out than is taken in (e.g. burning, respiration)
Terminology
Inhibitors - Something that slows down a chemical reaction, or prevents a chemical reaction from taking place.

Collision Theory -The collision theory states that when suitable particles of the reactant hit each other, only a certain fraction of the collisions cause any noticeable or significant chemical change; these successful changes are called successful collisions.
-
LoCoE - The Law of Conservation of Energy states that matter is neither created nor destroyed during a chemical reaction.
When a chemical reaction occurs, the bonds that hold a molecule together are either created or destroyed. There are two kinds of chemical reactions: Exothermic, which gives off heat and creates bonds, and endothermic, which stores heat and destroys bonds.
