Question

A chemist claims to have found a complex ion where the most intensely absorbed light is 371.0 nm. Estimate the crystal field splitting energy for this ion in kJ/mol.

Answer 1

the energy is E=h*c/wavelength for 1 photon

for a mole E = 6.0210^23*hc/Wavelength

E = 6.02 10^23 *6.610^-34*310^8/ 371*10^-9 =321283J

So 321.28kJ/mole
