Question:1
In the introduction of this experiment, there are several factors that are discussed as having an impact upon the rate of a reaction.

Pick one of these factors and come up with an original idea (not from the experiment or lecture) where the factor plays a role in the rate at which a chemical reaction occurs. Be sure to explain how and why your idea affects the rate of the reaction chosen.

For example: if you increase the surface area of a piece of coal by crushing it up, it will react with oxygen (burn) much more rapidly. This illustrates the relationship between surface area and reaction rate.






Question:2
There is a general rule of thumb that the rate of an observable chemical reaction doubles with every 10oC increase in temperature. How much would the rate of a chemical reaction change if the temperature were to increase by 40.0oC? Be sure to show your work.

Explanation / Answer

Question 1

Suppose that at any one time 1 in a million particles have enough energy to equal or exceed the activation energy. If you had 100 million particles, 100 of them would react. If you had 200 million particles in the same volume, 200 of them would now react. The rate of reaction has doubled by doubling the concentration.

Literary information:

Concentration and pressure

If the concentration or pressure of a chemical increases, there will be more particles within a given space.

Particles with therefore collide more often

As concentration or pressure increases, the rate of reaction also increases.

Question 2

Increase by 10
