The parameters describing chloride exchange on indium(III), determined by 35Cl N.M.R., are: k(298 K)= (8.8�0+4) x 106 s-1, ΔH? = 45.7�2.3 kJ mol-1 and ΔS? = 42�8 J mol-1 K-1; and k(298 K)= (2.0�0.1)x106 s-1, ΔH? = 37.7�1.9 kJ mol-1, and ΔS? = 3�6 J mol-1 K-1 in 10.95M and 7.00M aqueous hydrochloric acid respectively, calculated from the observed exchange rate kex4[InCl4(H2O)2-].��� For thallium(III) lower limits of kex(219 K) = 1.6 x 106 s-1 and 1.3 x 106 s-1 were obtained in 10.95M and 7.00M aqueous hydrochloric acid, respectively, where [TlCl6]3- is assumed to be the exchanging species.
