Calculate the initial molarity for the two reactants fe and SCN (with the correct number of significant figures for each of the solutions that went into cuvettes w1S. Recall that the initial molar concentration of the product is equal to zero at the start of the reaction MV, M, V, where M is the molarity of the stock solution V is the volume of the stock solution in liters M is the molarity of the diluted solution that is in the cuvette V, is the total volume in liters of the solution that was made for the cuvette a) (3) In the space below, show your calculation of the initial molarity of fe.

We will use the Beer Lambert Lew that relates absorbance of colored species to the molar concentration of the coloured speciet The Beer Lambert equation is shown below. 130Calculate the concentration of the known solution of resc. This known solution was made in Part A Step in the experimental procedure in this procedural step, you measured out 2.00 mL of 0.00200 M NSC and then added 1000 ml of 0.200 Mre/No.1, and 8.00 mt oft water, for a total wolume of resulting solution of 20.00 mL in the space below, show your complete calculation for the concentration of tescil in the known solution (remember to use the correct number of significant figures Fel + SCN - FeSCN Hint for this cation recall that the NaSC Amiting reestant (there is a large excess of Fe(NOJ, to ensure that at the SC extentially converted into Fest base is complete when an equal number ces have combined at what is known as b) (6) Because absorbance for a given solution containing FeSCN is proportional to molar concentration of fesc" (as per Beer's Law), use a simple proportionality equation shown below to solve for Equilibrium concentration of resc in eachusette, Show your work for cuvette al in the secm below, and put in the Equilibrium values for frescu") in each cuvette into the respective it table AC where A is the measured absorbance (this is a unitless quantity the product is a constant composed of two separate constants called the molar absorptivity (e) and the thickness of the absorbing medium (b) C is the molar concentration of the absorbing species [FeSCN).

Examine the last column in your ICE tables and notice that this concentration at represents the Change in Fec molar concentration, Now, enter in the Change in molarities of Fec, Feand SCN into the ice table for each cuvette (Tables 3-7). Be sure to indicate the sign of the individual values Determining Equilibrium Concentrations 3. (4) Next, calculate the Equilibrium molarities for fe and SCN from the values you have entered into the ICE table for each cuvette, using Initial molarity and the Change in molarity for these remaining species Show your calculations below for the Equilibrium molarities for Fe" and SCN for cuvette #1. Enter all the Equilibrium molarities for each cuvette in the ICE Table for the respective cuvette. This step will complete the ICE Table for each cuvette.
