In this next section we will investigate reversible reactions in more detail by observing by changing the volume of the container. The reaction we will look at is R + G RG. In place of the microscopic representation we will view the reaction by tracking the amount of reactants and products using a chart recorder.
Experiment #1: Before starting the movie on the right note the Initial amounts of R, G and RG. When you start the movie you will see a chart recording depicting the relative amounts of all three chemical species. NOTE: That even though there are two reactants, their concentrations are the same so the chart recording only has a single line for the reactants. Once the Enable Reaction button is clicked you will see products being formed. View the movie on the right and consider the following questions:
9. Can you set up the RICE table (Reaction, Initial Condition, Change Condition and Ending Condition) with the Initial amounts of R, BG, RG and B? Answer
10. What happens when the Resume button is selected? Answer
View the movie on the right and answer the following question:
11. Describe what happens when the Enable Reactions button is selected? Answer
12. Continue the RICE table started in Question 9 by including the amounts of R, BG, RG and B after the chart recording stops (Ending amounts). Answer
Experiment #2:
In the next movie the initial amounts of BG, RG and B are the same as the Ending amounts from Experiment #1 and the Initial amount of R is changed by increasing its amount to 2.00 moles.
13. Setup the new ICE table with the Initial amounts of R, BG, RG and B in Experiment #2. Answer
View the movie on the right and answer the following question:
14. Complete the ICE table with for Experiment #2 with the Ending amounts of R, BG, RG and B and the Change amounts. Answer
RG. In place of the microscopic representation we will view the reaction by tracking the amount of reactants and products using a chart recorder.
