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 reaction. |
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 | States that is 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 unit of time. |
Inhibitor | Slows down reaction rate or prevents reaction from happening. |
