Consider the quenching of an organic fluorescent species with 0 = 6.0ns by a d-metal ion

Question:

Consider the quenching of an organic fluorescent species with τ₀= 6.0ns by a d-metal ion with k_Q = 3.0×10⁸dm³ mol⁻¹ s⁻¹. Predict the concentration of quencher required to decrease the fluorescence intensity of the organic species to 50 per cent of the unquenched value.
