Question

The molecu le 2,2'-bipyridine (1, bpy) forms a complex with the Ru2+ ion. Ruthenium(ll) tris-(2,2'-bipyridyl), Ru(bpy)3,2+(2), has a strong electronic absorpt ion at 450 nm . The quenching of the * Ru(bpy)3 2+ excited state by Fe(OH2)63+. in acidic solution was monitored by measuring excited state lifetimes at 600 nm. Determine the quenching rate constant for this reaction from the following data:
