-The rate of a chemical reaction is either the measure of the rate of which a reactant disappears or the measure of the rate of which a product appears
-Chemical reactions don’t all happen at the same rate some reactions are much slower than others, they can be finished in less than a second or even years
- A catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any chemical change
-A catalyst can help with the geometry but it’s NOT consumed by it. What this means is that in order for a reaction to occur the molecules must be oriented in the proper geometry.
-The collision theory of reactions :Molecules must collide in order to react. In a successful collision, existing bonds are broken as new bonds are formed and the reactants are transformed into products
-An activated complex is the highest point on a reaction profile it’s the transition state or the activated complex.
- When it is endothermic the reactants are at a lower energy than the products
-An endothermic reaction absorbs heat as the reactions continues
- when it’s exothermic the products are at a lower energy than the reactants.
-An exothermic reaction releases heat as the reaction proceeds
-H) for an exothermic reaction is negative
- The temperature, concentration, particle size, and the inhibitor all affect the rate of the chemical reaction
-Le Châtelier’s principle is that if stress is applied to a system in a dynamic equilibrium the system changes to relieve stress

-H) for an exothermic reaction is negative
- The temperature, concentration, particle size, and the inhibitor all affect the rate of the chemical reaction
- When the temperature is higher the particles hit each other more often and with more energy which will cause them to react faster : Heat is either a product or reactant
- Concentrated particles will collide more and react faster :if you increase it the equilibrium shifts the product side
- The greater the surface area, the faster the particles can collide.
- An inhibitor slows down or prevents a chemical reaction from occurring.
-Le Châtelier’s principle is that if stress is applied to a system in a dynamic equilibrium the system changes to relieve stress
