Do not press the RETURN or ENTER key while you are answering these questions. Your browser will interpret either the same as clicking on the Submit key.

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 you will watch a 'movie' of a reaction occuring at the particulate level. To watch the movie of the reaction click on the movie to play. After watching the movie you will answer a few questions. You may wish to repley the movie as you address the questions below.

Simulation

1. Click in the movie window and observe the simulation of the chemical reaction. Describe what you observe happening in the sample region. Use some or all of the following terms in your description: atom, molecule, particle, collision, effective collision, speed, energy, reactant(s), product(s), and intermediate(s).

 


2. Complete Table I below, with the number and kind of particles in the sample region before the reaction begins. You may want to move the movie controlbar all the way to the left to the very beginning of the movie.

Table I

Number

G

B

G2B

Now allow the movie to play and observe the interaction in the sample region until no further change is observed. Record in Table II below, the number and kind of particles in the sample region.

Table II

Number

G

B

G2B

3. What criteria did you use to determine when the reaction in the sample region was finished.

4. Write an overall balanced chemical equation that best describes the reaction you observed in the sample region.

5. Does the overall balanced chemical equation clearly describe the conversion of reactants to products. Briefly explain.

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

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