Answer all of the questions below. If you do not know an answer enter CNA. However, it will help me the most if you answer each question with your best intuition/idea about what would be a reasonable answer.

In this BCE we are interested in asking the question, how does a chemical reaction proceed from reactants to products. Use this video for Questions 1 - 3.

1. Based on what you observe in the sample region (the box in the left portion of the window), record the number and the initial concentration of R, BG, B and RG particles in the table below.

 
R
BG
B
RG
# of particles
Concentration (M)

2. Play the movie and allow the simulation to run. Record your observations of what is happening. Use some or all of the following terms in your description: atom, molecule, particle, collision, effective collision, speed, energy, orientation, reactants and products.

3. Write a balanced chemical equation for the reaction you have observed in this simulation. (Simply the equation so that no common particles are on both sides of the equation and it represents the lowest ratio of whole numbers of particles.)

In this BCE we are interested in asking the question, how does a chemical reaction proceed from reactants to products. Use this video for Questions 4 - 6.

4. Let's look at a second movie of a reaction. Based on what you observe before the reaction begins in the sample region (the box in the left portion of the window), record the initial number and the concentration of G, B, G2,GB, G2B, and B2 particles in the table below.

 
G
B
G2
GB
 G2B B2
# of particles
Concentration (M)

5. Play the simulation to run. Describe what happens in this reaction. (You may want to restart the reaction to watch the reaction more than once.)

In what way(s) is this reaction different from the first reaction.

6. Write a balanced chemical equation for the reaction you have observed in this simulation. (Simply the equation so that no common particles are on both sides of the equation and it represents the lowest ratio of whole numbers of particles.)

7. Is there anything about the questions that you feel you do not understand? List your concerns/questions.

8. If there is one question you would like to have answered in lecture, what would that question be?
