Rates

2. Greek letter Δ written before a quantity indicates a change in the quantity
5. substance that slows down a reaction
7. describes reactions where products are favored
8. mathematical expression that shows the relationship between rate of a reaction and the concentration of the reactants
9. change in concentration of a reactant or product per unit of time, generally expressed as mol/(L·s)
10. value for Gibbs free energy when the reaction is nonspontaneous
11. describes reactions where products are NOT favored
13. type of catalyst important in living organisms
15. term for the minimum amount of energy that reacting particles must have to lead to a reaction
16. randomness of all things in the universe

1. name of the theory that states atoms, ions, and molecules must collide properly in order to react
3. type of reaction where products have lower energy than reactants
4. energy that may be converted into work in a system that is at constant temperature & pressure
6. value for Gibbs free energy when the reaction is spontaneous
12. type of reaction where reactants have lower energy than products
14. increases the rate of a chemical reaction without being consumed in the reaction - it is not a reactant or product
