If a complex ion has a crystal field splitting energy of 410 kJ/mol,what is its maximum absorption?
A) 425 nm
B) 353 nm
C) 292 nm
D) 231 nm
E) 193 nm

Question

Quizplus · Accepted Answer

The maximum absorption wavelength of a complex ion is related to its crystal field splitting energy by the equation λ(max) = hc/Δo. Plugging in the given value for Δo, we get λ(max) = (6.626 x 10^-34 J s) x (2.998 x 10^8 m/s) / (410,000 J/mol) = 4.839 x 10^-19 m = 292 nm. Therefore, the correct choice is C) 292 nm.
