Find the average value of K eq, the standard deviation, and the relative error (standard deviation divided by the average).JWB-1 Spectrophotometric Determination of K f Formal Report Heather Ryan Abstract.This is to ensur e that all of the K SCN is used up in the reaction.From our spectrophotometric data,. 30 Chemistry 1B Experiment 7.Given your value of K, go back and check the validity of the assumption you made in Part 3.Once you have actually determined K eq, you must return to this assumption and verify its validity.Discuss how good the assumption was and how the assumption affected the calculated values of K eq.Because the stoichiometry is 1:1:1, the amount of reactant consumed is equal to the amount of product formed.Using the graph I prepared from the data on Page 142, the absorbance I calculated in.Use volumetric pipets and a 10 mL volumetric flask to prepare each of the following five solutions.
