2. At equilibrium, which had a greater volume?
Forward Reaction

4.
What was the effect on equilibrium volumes when you started with no reactants and 25.0-mL of products compared to
the other way around?
5.
Graph your results for both experiments. In the first graph, plot the transfer number (1 through X) on the x-axis and the
volumes (mL) for both reactants and products on the y-axis. In the second graph, use the second set of data. Plot the
transfer number (1 through X) on the x-axis and the volumes (mL) for both reactants and products on the y-axis. Use
different colors for products and reactants and provide a key. Be sure to label your axes as well as your graph.
Analysis and Conclusion:
1.
Was equilibrium established in both
experiments? If it was, what can you
conclude about equilibrium?
2.
What variable determines whether there
was a greater volume of reactants or
products at equilibrium?
3.
Why would this system be called a
dynamic equilibrium?
