Flashcards in Ap Chem. Ch.14 Deck (10)
The more HOMOGENEOUS the mixture of reactants, the ______ the molecules can react.
- usually oppositely charged ions react ____.
- bonds with HIGH BOND ENERGIES are harder to break and _____.
As the concentration of reactants increase
At higher TEMPERATURES, reactant molecules have more kinetic energy, move faster, and ________more often and with_____energy.
Each 10 degrees increase apporimately does what to the reaction rate?
Ex: if the temperature increses by 20 degrees, the rate of reaction is quadripuled.
How do Catalysts speed up reactions?
By changing the mechanism of the reaction
Catalysts are NOT part of the overall equation and ____ consumed during the course of the reaction.
Except for substances in the gaseous state or solution, where do the reactions occur?
Reactions occur at the boundary between phases
What happens to the rate of reaction as the suface area increases?
Increase in surface area increases the chance for collision, making the RATE FASTER!
