Equilibrium Constant Determination You will have to determine the equilibrium constant for the reaction between aqueous iron(III) ion and thiocyanate ion. The equilibrium equation is given below: Fe3+ (aq) + NCS– (aq) <---> FeNCS2+ (aq) yellow colorless red The absorbance of light is measured using a spectrophotometer. The higher the absorbance, the higher the concentration of FeNCS2+ present. At room temperature, 5.00ml of 0.200M iron(III)nitrate solution was mixed with 5.00ml of 0.200M potassium thiocyante solution. The absorbance of this mixture was 0.55. A 1cm thick cuvette was used. What is the path length (b) ? What is the molar extinction coefficient (E) ? What is the equilibrium concentration of iron(III)thiocyante of our solution? What are the equilibrium concentrations of Fe3+ and SCN- in our solution? Please help I am so confised!
