Question 1 (a) [40 marks] Two homogeneous (i.e. soluble) Fe complexes are dissolved in solution. Both complexes are present at a concentration of 0.004 M each. Complex 1 exhibited an absorption band with a max value of 320, an Absorbance maximum of 0.8, and a Full Width Half Maximum value of 40 nm. Complex 2 exhibited an absorption band with a with Amax of 375, an Absorbance maximum of 0.60, and a Full Width Half Maximum value of 25 nm. (i) What is the energy of the electronic transitions that results in the absorption band observed for Complex 1 and Complex 2? [4 marks] (ii) Based on the information provided, how much larger is the molar absorption coefficient of Complex 1 than Complex 2. [6 marks] (iii) Estimate the absorbance value exhibited by Complex 2 at a concentration of 0.045 M, assuming all other parameters remain unchanged.
