Abstract

The rate of the oxidation of formic acid by thallium(III) in (Li, H)ClO4 solutions is not affected by variation in hydrogen ion concentration and the experimental rate law,

$$\frac{{ - d\left[ {T\left( {III} \right)} \right]}}{{d t}} = \frac{{k_1 K\left[ {T\left( {III} \right)} \right]\left[ {HCOOCH} \right]}}{{1 + K\left[ {HCOOH} \right]}}$$

is consistent with the mechanism which requires the formation of intermediate complex [HCOOHTl]3+ in a rapid preequilibrium followed by its slow decomposition to yield the final products. At 75°,k 1 andK have the values of 16±1×10−5 sec−1 and 7.3±0.5M −1 resp.
