PROCESSING THE DATA 1. From the Pre-Lab step 2 Table, copy the calculated initial concentrations of Fe and SCN into the second and third rows of the following table. (Part Il) Use the absorbance values, along with the best fit line equation of the standard solutions in Part I to determine the [FeSCN at equilibrium for each of the mixtures that you prepared in Part II. Complete the table below and give an example of your calculations Test tube number SCN o.38o 2612 slope 2612 2612 2612 2. Set up an ICE table for the iron(III), thyocyanate equilibrium, and calculate the value of Ky for the reaction in cach of the four test tubes using the data in the above table for step 1 in Processing the Data. Using the data from Test tube I show the calculation for Key. Calculate the average value for Koy and the standard deviation for the average value of the four Koy values. 2A
