Abstract

Kinetics of chemical reactions in the O–S system in the course of eruptions of on Io’s volcanoes is investigated. A kinetic method of conditions determination of the cessation of chemical reactions on Io is developed. It is shown that the S2 abundance is frozen at higher temperatures and pressures, than S, SO, SO2 abundances. For profound study of chemical reactions kinetic in the course of the Io volcanoes eruptions a physical-chemical model is needed to built. It allows to estimate a velocity of outflow of volcanic gases during volcanoes eruptions.
