Vedclass · Answer

(A) The stability of a compound is inversely proportional to the equilibrium constant $(K)$ of its decomposition reaction.$A$ lower value of $K$ indicates that the equilibrium lies far to the left,meaning the compound has a lower tendency to decompose into its elements.Comparing the given equilibrium constants:$K(NO_2) = 6.7 	imes 10^{16}$$K(NO) = 2.2 	imes 10^{30}$$K(N_2O_5) = 1.2 	imes 10^{34}$$K(N_2O) = 3.5 	imes 10^{33}$Since $NO_2$ has the smallest equilibrium constant value,it is the most stable oxide among the given options.Therefore,option $A$ is the correct answer.

Which of the following oxides of nitrogen is the most stable?
