Question

Part A

What is the relationship between the magnitude of (crystal-field splitting energy for an octahedral crystal field) and the energy of the dd transition for a d1 complex? (only 1 right answer)

is tour times as big as the energy of dd transition.

B. Calculate in kJ/mol if a d1 complex has an absorption maximum at 590 nm.

is equal to the energy of dd transition. The energy of dd transition is twice as big as . . The energy of dd transition is four times as big as . . is twice as big as the energy of dd transition.

is tour times as big as the energy of dd transition.

B. Calculate in kJ/mol if a d1 complex has an absorption maximum at 590 nm.

Explanation / Answer

delta is equal to energy of d-d transition.

B) wavelength lamda = 590 nm = 590 x 10^-9 m

for 1 mole E = nhc/lamda = ( 6.023x10^23) x ( 6.625x10^-34) x ( 3x10^8) / ( 590x10^-9)

        = 202893 J = 202.9 KJ/mol
