| Abstract: | The inner layer entropy of formation of metal/solution interface (△S~(m-d)) as a function of electrode charge (σ) is derived by using statistical mechanics based on the model of dipole orientation distribution presented in previous paper. the relating curves of △S~(m-d) with σ has been calculated for three different interface systems, namely, the Hg/methanol, Hg/ethylene carbonate and Hg/aqueous solution. According to the present results, the variation in △S~(m-d)(σ) of Hg/methnol interface seems to be chiefly depended on the structure of solvate layer and its dipole orientation distribution. But for the interface of the Hg/ethylene carbonate or the Hg/aqueous, the change of ΔS~(m-d) with σ would be regarded as due to the contribution of surface Hg atoms. |
