Reactive and inelastic collisions of ultra-cold molecules has generally been observed to follow a universal rate law described by the quantum Langevin model. The salient feature of this law is an independence of the reaction probability from the short-range physics of the interaction. We report on reactive and inelastic collisions of $^6$Li$_2$ dimers in several ro-vibrational states of the a(13Σ+u ) potential. While the v = 0, 5, 8 are observed to decay at the universal limit, decay of the |v = 9, N = 0⟩ state exhibits a deviation from universality, opening up the possibility of using external magnetic fields to tune the reaction rate.
