Bean Equilibrium Activity

Procedure:

1. Decide who is going to be Reactants (A) and who is going to be Products (B).

2. Count how many beans you have in your bag and enter into Initial Number of Beans for Reactants (A). Write 0 for Initial Number of Beans for Products (B).

3. Multiply your Initial Number of Beans for A by 1/3 to represent how many As are becoming Bs. Record that number as a negative (A is losing) in Beans moved for Reactants. Record the same number as a positive (B is gaining) in Beans moved for Products. Record Final Number of Beans after those beans have been moved for both Reactants and Products.

4. Your Final Number of Beans in each row will now become the Initial Number of Beans for next round.

5. Now multiple your Initial Number of Beans for A by 1/3 to represent how many As are becoming Bs and multiply your Initial Number of Beans for B by 1/4 to represent how many Bs are now become As. Record many As are becoming Bs and Bs become As to determine how many total beans are moving. Then determine final Number of Beans for both As and Bs.

6. Repeat steps until you reach equilibrium.

7. Write a summary of what you learned and see about your final amounts of reactants and products as well as any changes that you are observing at equilibrium.

8. Determine equilibrium equation for beans and solve for K.
