Term Definition
Activated Complex Intermediate phase between reactants and products which is short-lived, has high energy and is very unstable.
catalyst Unchanged in a reation which speeds up the reaction rate and lowers activation energy.
collision theory In order for a reaction to occur, the reactants must collide with enough KE and the proper angle.
Exothermic release energy on the right
Endothermic absorb energy on the left.
Effective Collision causes a reaction with the right amount of KE.
enthalpy The potential energy in a reaction
kinetics the rate of chemical reactions and the mechanisms by which they occur.
Reaction Mechanism The sequence of reactions by which a chemical change occurs
Activation energy The minimum amount of energy needed to cause a reaction.
Heat of reaction Change of heat-Potential Energy of product minus Potential energy of reaction
Speed up reaction increase temperature, increase pressure, catalyst, gasses, increase concentration, increase surface area.
Concentration Increase reaction rate, and frequency of collisions
pressure gasses-increase reaction rate and collisions
Temperature Increase Kenetic Energy and reaction rate.
