    Which of the following oxide of nitrogen is most thermally stable?

    A) \[{{N}_{2}}{{O}_{5}}\]                   

    B)        \[{{N}_{2}}O\]

    C)        \[NO\]                                 

    D)        \[{{N}_{2}}{{O}_{3}}\]

    Correct Answer: C

    Solution :

    Nitric oxide \[(NO)\] is decomposed at\[{{900}^{o}}C\]. So, it is the most thermally stable oxide of nitrogen                 \[2NO\xrightarrow{{{900}^{o}}C}{{N}_{2}}+{{O}_{2}}\]
