In questions 2, 3, and 4, explain how the following actions would cause the quantity in question to be too large, too small, or no change. 2. An error was made in preparing the Fe(NO3)3 solution. Its concentration was 0.250 molar but was labeled as 4.300 molar. a. How would the slope of the calibration curve (absorbance on the "y" axis versus concentration of [Fe(SCN)]2+ on the "x" axis) be affected? b. How would this concentration error affect the calculated value of the equilibrium constant for the complex, [Fe(SCN)]2+? 3.How would your calculated value of Kc compare to the actual vale if the determination of absorbance were done on a solution that had been placed in a cell that was wet on the inside with rinse water? Explain. 4.When adding the solution of HNO3 from the buret in Step 14 to beaker 4, you know that you added 2.5 mL instead of 1.5 mL for a total volume of 11.0 mL. How would the calculated value of the equilibrium constant be affected for this sample?
