Order the following chemical formulas to decrease the stability of molecules: H2O(g), SO2(g), NO(g).
The following thermochemical constants are known:
?f H0 H2O( g ) = -241,6 kJ/mol;
?f H0 SO2 ( g ) = -297 kJ/mol;
?f H0 NO( g ) = 90,29 kJ/mol;

greater the enthalpy of formation greater the stability
hence decreasing order of stability is SO2(g) > H2O(g) > NO(g) ( endothermic compounds are less stable than exothermic compounds since NO is an endothermic compound is least stable, for SO2(g) enthalpy of formation is highest hence it is highly stable 2nd highest is water (g).)
