Temperature and Rate
-Generally, and temperature increases so does the reaction rate
-K is temperature dependent

The Collision Model
-In a chemical reaction the bonds between atoms are broken and new bonds are formed
-molecules can only react if they collide with each other
-They must also collide with the correct orientation and with enough energy to break break the old bonds and form new ones.

-The high point of the reaction is called the transition state.
-The species present at the transition state is called the activated complex
-The energy gap between the reactants and the activated complex is the activation energy barrier.
- since the products potential energy is lower than the reactants potential energy, this reaction is exothermic.
-This means that it increases the entropy of the surroundings of the reaction.
-The enthalpy of this reaction is less than zero because it is an exothermic reaction.
