The more HOMOGENEOUS the mixture of reactants, the ______ the molecules can react.

Faster

1

Chemical identity
- usually oppositely charged ions react ____.
- bonds with HIGH BOND ENERGIES are harder to break and _____.

Fast
Slower

2

As the concentration of reactants increase

Collide

3

At higher TEMPERATURES, reactant molecules have more kinetic energy, move faster, and ________more often and with_____energy.

Collide
Greater

4

Each 10 degrees increase apporimately does what to the reaction rate?

Doubles it
Ex: if the temperature increses by 20 degrees, the rate of reaction is quadripuled.

5

How do Catalysts speed up reactions?

By changing the mechanism of the reaction

6

Catalysts are NOT part of the overall equation and ____ consumed during the course of the reaction.

Are not

7

Except for substances in the gaseous state or solution, where do the reactions occur?

Reactions occur at the boundary between phases

8

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!

9

How can rates of reactions be determined?

By monotoring the change in concentration of either reactants or products as a function of time.
