Unit 7 Vocabulary
| Term | Definition |
|---|---|
| Entropy | Measure of degree of randomness as particles move. |
| Chemical Equilibrium | Rate of forward reaction equals rate of reverse reaction and the concentrations of products and reactants remain unchanged. |
| Activated Complex | The maximum energy point along the reaction path. |
| Activation Energy | The minimum energy that must be input to a chemical system with potential reactants to cause a chemical reactant. |
| Collision Theory | Qualitatively explains how chemical reactions occur and why reaction rates differ for different reactions. |
| Catalyst | A substance that speeds up a chemical reaction, but is not consumed by the reaction. |
| Reversible Reaction | Products can react to re-form the reactants. |
| LeChatelier's Principle | If a stress is applied to a system at equilibrium the system shifts in the direction that relieves the stress. |
| Reaction rate | Change in concentration of a reactant or product per uint of time. |
| Inhibitor | Slows down reaction rate or prevents reaction from happening. |
