The Venusian atmosphere is the most complex and poorly understood of any of the inner planets. It consists of layers including sulfuric acid clouds and dense regions of supercritical CO2 and N2 with trace amounts of other gases such as SO2, COS, H2O, HCl, and HF. Furthermore, the surface of Venus is known to be geologically active with volcanic activity constantly releasing gases into the atmosphere and lava flows. Computational thermodynamics is a useful tool for unraveling the atmospheric chemistry and atmosphere/surface interactions on Venus. Several examples will be discussed. Several atmosphere/surface reactions have been proposed to buffer the SO2 content in the atmosphere (Treiman and Bullock, 2012, Icarus 217, 534-541) and these are best analyzed with computational thermodynamics. Another important question is the thermodynamics of the CO2/N2 fluid, which can be determined with a multi-component supercritical fluids thermodynamic database (Shi and Saxena, 1992, Am Mineralogist 77, 1038-1049).
