Give a characteristic of the chemical process and indicate the conditions for its displacement

Give a characteristic of the chemical process and indicate the conditions for its displacement in the direction of the reverse reaction: H2S ↑ + O2 ↑ ⇆SO2 ↑ + H2O + Q

A chemical reaction takes place between substances such as hydrogen sulfide or hydrogen sulfide acid and oxygen. As a result of the reaction, substances are formed: tetravalent sulfur oxide and water. The reaction proceeds according to the type of substitution. This chemical reaction takes place with the release of heat and is therefore exothermic. The above reaction is reversible, it can also be noted that it is homogeneous, since two gases enter into the reaction. The molecular equation of the reaction can be written as follows:

H2S + O2 = SO2 + H2O + Q.
