RESULTS AND CALCULATIONS 1. Part (II) Use the calibration equation from Part 1, Step 9 and the absorbance reading for your unknown solution to determine (SCN). 2. Part (II) Compare your experimental (SCN ), of your unknown, with the actual [SCN ). Suggest reasons for the disparity. 3. Part (III) Use the absorbance values, along with the best fit line equation of the standard solutions in Part I to determine the [FeSCN2] at equilibrium for each of the mixtures that you prepared in Part III. Complete the table below and give an example of your calculations. Test Tube 2 3 4 5 [FeSCN) Experiment 5: The Determination of an Equilibrium Constant 4. Part (III) Calculate the equilibrium concentrations for Fel and SCN for the mixtures in Test Tubes 2-5 in Part III. Complete the table below and give an example of your calculations. Test tube 3 5 [Fe") [SCN) 2 5. Calculate the value of Leg for the reaction. Explain how you used the data to calculate Keq. 6. Explain what the Keg value calculated in #5 means in terms of reactant particles vs. product particles 7. Explain what would happen to the ratio described in #6 if the concentration of the reactant was doubled. 8. Identify any sources of error that would account for your answer. Are they reasonable? Comment on the error and results.
