Chapter 15 Le Chtelier's Principle Worksheet Open the Le Chtelier's Principle activity (Section 15.6, Figure 15.9) to complete this worksheet. 1. Start with the default settings where K = 1.00. a. Write the K expression based on the chemical equation in the upper right corner. b. Under the initial conditions of [A] = 2.00 M, and [B] = 4.00 M, is the reaction at equilibrium? How can you tell? c. Compare how Q is affected by dragging the [A] slider versus dragging the [B] slider? d. Describe how the particle view changes when dragging the [A] and [B] sliders. e. Set the initial concentrations of both [A] and [B] to 3.00 M. Is the reaction at equilibrium under these conditions? How can you tell? f. Before pressing play, predict which direction the reaction will shift to regain equilibrium, and how the particle view will change during this shift. g. Press play to verify your predictions. What are the values of [A] and [B] when the reaction reaches equilibrium again? h. Complete an ICE table (with values, not variables) showing the change that occurred between parts e and g.
