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...

solve all 3 dont waste my answer 1. Check Beer's Law by plotting absorbance vs molar concentration using 2. Is Beer's Law valid for this system? Explain your answer. 3. If Beer's Law is valid, the value of "E" should be constant. Use A-ECPL or E = A/(EL) and the data from Table II to calculate values of E for the five solutions below. The value of L is normally 1 cm so E - A/C in this experiment. Table...
