WebFormates act as intermediates in HCOOH decomposi-tion; their formation limits rates on the nobler metals (Au, Ag) and their decomposition on the others.[10] Au catalysts give lower areal rates than other metals because of its inertness in HCOOH dissociation, evident from its first-order HCOOH decomposition kinetics.[12] Small Au clusters WebThe S0, T1, and S1 potential energy surfaces for the HCOOH dissociation and isomerization processes have been mapped with different ab initio methods. The wavelength-dependent mechanism for the HCOOH dissociation was elucidated through the computed potential energy surfaces and the surface crossing points. The HCOOH …

WebAug 14, 2024 · The larger the Ka, the stronger the acid and the higher the H + concentration at equilibrium. Like all equilibrium constants, acid–base ionization constants are actually measured in terms of the activities of H + or OH −, thus making them unitless. The values of Ka for a number of common acids are given in Table 16.4.1.
