Vedclass · Answer

(D) The given reactions represent the decomposition of nitrogen oxides into $N_2$ and $O_2$. Stability is inversely proportional to the equilibrium constant $(K_c)$ of the decomposition reaction. $A$ higher $K_c$ value indicates a greater extent of decomposition,meaning the oxide is less stable. $A$ lower $K_c$ value indicates a lesser extent of decomposition,meaning the oxide is more stable. Comparing the given $K_c$ values: $1 	imes 10^{15} Since $2NO_2 ightleftharpoons N_2 + 2O_2$ has the lowest $K_c$ value,$NO_2$ is the most stable among the given options.

At $273 \, K$,which of the following oxides is the most stable?
