(https://phet.colorado.edu/en/simulation/legacy/reversible-reactions) 2) Play with the simulation. Click on EVERYTHING! 3) Answer the following questions: I 1) Put some number of balls (>50) in one of the wells. In a table, record the number of green and red balls in each well as a function of time. (Suggested time length: 5 minutes, suggested intervals: 15-20 seconds) Paste the table into this document. (Google spreadsheet will work well for this.) 2) Paste in a graph of your data. Describe the shape of the graph and what it means in terms of the red and green balls. Consider the ratio of red balls to green balls. How does that change over time? 3) After some amount of time, this simulation reaches a dynamic equilibrium state (DES). That is, a situation in which components of a system are moving but no net change is observed. Describe how this simulation fits this model in terms of the amount of red and green balls.
