A 35 mL solution of K3Fe(C2O4)3 is irradiated with monochromatic light at 468 nm for 30 min. The solution is then titrated with 1,10-phenantroline to form the red complex of 1,10-phenanthroline- Fe2+. THe absorbance of this complex ion measured in a 1 cm cell at 510 nm is 0.65 ( €510 = 1.11 x 104 M-1 cm-1). Assume that the quantum yield for the decomposition at this wavelength is 0.93, and calculate the number of einsteins absorbed per second and the total energy absorbed.
