Short summary
The hydration of SO3 to produce H2SO4 is an important process in the atmosphere. Using quantum chemical calculations, we investigated the catalytic role of oxalic acid in the SO3 hydration reaction. The results show that oxalic acid is effective in facilitating the hydration of SO3 to form H2SO4. The kinetic analysis result indicates that the oxalic-acid-catalyzed SO3 hydration can play an important role in the upper troposphere.
