KINETICS OF THE OXIDATION OF MERCURY(I) BY …

The rate-determining step of the reaction appears to be a 'two-electron transfer' between a mercury atom, formed by the dismutation of Hg2++, and a hydrolyzed thallium ion, i.e. Hg + TlOH++ → Hg++ + Tl+ + OH−. The rate constant, k, of this reaction is given by k = 1016±2 exp[−14000 ± 3000/RT] liters mole−1 sec.−1.H+ retards the reaction by opposing the hydrolysis of Tl+++, while ...
