| collision theory | IF they have enough energy, particles can form chemical bonds by colliding |
| activation energy | minimum energy particles must have in order to react |
| activated complex | arrangement of atoms at the peak of the energy barrier |
| transition state | another name for activation complex |
| catalyst | a substance that increases the rate of a reaction |
| inhibitor | a substance that interferes with a catalyst |
| reversible reaction | simultaneous reaction in both directions |
| chemical equilibrium | forward and reverse rxns take place at same rate |
| forward reaction | reaction moves to right/toward products |
| reverse reaction | reaction moves to left/toward reactions |
| LeChatelier's Principle | stress applied to a system causes the system to change in ways that relieve the stress |
| Free energy | energy that is available to do work |
| spontaneous reactions | naturally favor the formation of products |
| non-spontaneous reactions | do not favor the formation of products |
| entropy | chaos/the disorder of a system |
| law of disorder | things tend toward maximum chaos/disorder |
| exergonic | releases free energy: a spontaneous reaction |
| endergonic | absorb energy: non-spontaneous reactions |
