Chem Unit 7
| Question | Answer |
|---|---|
| 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 miniimum energy that must be input to a chemical system with potential reactants to cause a chemical reaction |
| collision theory | qualitatively explains how chemical reaction 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 reform the reactants |
| Le Chatelier'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 unit of time |
| inhibitor | slows down reaction rate or prevents reaction from happening |
