    When sodium nitrate is heated above\[{{6000}^{o}}C\], then:

    A)  only \[N{{a}_{2}}O\] is formed

    B)  only \[{{N}_{3}}\] is formed

    C)   only \[{{O}_{2}}\] is formed

    D)   all are formed

    Correct Answer: D

    Solution :

    On heating \[NaN{{O}_{3}}\] above \[{{600}^{o}}C\,\,N{{a}_{2}}O,\,\,{{O}_{2}}\] and \[{{N}_{2}}\] all is obtained as: \[4NaN{{O}_{3}}\xrightarrow{{{800}^{o}}C}2N{{a}_{2}}O+5{{O}_{2}}+2{{N}_{2}}\]
