In-Lab Question 6. Using your calibration curve from Part A and your absorbance data from Part B, what is the equilibrium concentration of [FeSCN 2+ ] in Solution 1B. Remember that the y value from the calibration curve represents the absorbance and the x value the concentration. Enter your result in Data Table B. In-Lab Question 7. Complete the reaction table for Solution 1B below. (All entries should be in molarity .) Fe 3+ ( aq ) + SCN ( aq ) FeSCN 2+ ( aq ) [initial] 3.30e-4 0.000330 1.00e-3 0.00100 0. 0.00 [ ! ] -7.50e-5 -7.50e-05 -7.50e-5 -7.50e-05 7.50e-5 7.50e-05 [final] 2.55e-4 0.000255 9.3e-4 0.00093 7.50e-5 7.50e-05 In-Lab Question 8. From the equilibrium concentrations in the table for Solution 1B above, calculate the equilibrium constant for the reaction. (Enter your answer to two significant figures.) K = 320 320
