Question

Quizplus · Accepted Answer

The crystal field splitting energy (Δ) can be calculated using the formula Δ = hc/λ, where h is Planck's constant (6.626 x 10^-34 J·s), c is the speed of light (3.00 x 10^8 m/s), and λ is the wavelength in meters. Convert 580 nm to meters (580 x 10^-9 m), then calculate Δ in joules and convert to kJ/mol using Avogadro's number (6.022 x 10^23 mol^-1). This gives approximately 206 kJ/mol.
