4.81 mL of 0.00200 M Fe(NO3)3, 2.85 mL of 0.00200 M KSCN and 2.34 mL of distilled water were mixed. The resulting solution was allowed to attain equilibrium at 24 oC. The absorbance of the equilibrium solution was recorded, and the [FeSCN2+] was determined graphically to be 7.58 x 10-5 M. Part A: Calculate the number of moles of Fe3+ initially added to the solution. Part B: Calculate the number of moles of FeSCN2+ formed in the solution at equilibrium....

What's the concentration of [FeSCN2+] using limiting
reactant theory and equation?
For each test tube solution enter the initial concentration of Fe+ and SCNthe equilibrium concentration of FeSCN2: into the ICE table given. Complete entries for the rest of the table and calculate the K value for each of the tables. The values of K should be confined to a narrow range to reflect constancy. Comment on the quality of your work in this regard and calculate the average K....

Beers law solve for E3 and E4 showing work
Part II. Equilibrium Constant Calculations
Calculate the initial moles of Fe3+ and SCN- for solutions E2
through E6 and record these values in the table on your Data Sheet.
You obtain the moles of the reactants by multiplying their molarity
by the volume (in L) of their solution used.
Determine the equilibrium concentration of FeSCN2+ for each of
the solutions E2-E6 from your Beer’s Law plot. Using these
equilibrium concentrations, the...
