a substance that interferes with the action of a catalyst
activation energy
the minimum amount of energy particles must have in order to react

a reaction that can go from the products and produce the reactants that were originally in place
catalyst
a substance that is used to increase the rate of reaction by lowering the activation energy barrier
free energy
the energy that is available to do work
activated complex
an unstable arrangement of atoms that briefly exist at the peak of the activation energy barrier
chemical equilibrium
