    \[{{N}_{2}}{{O}_{4}}\]equals

    A) \[{{N}_{2}}{{O}_{4}}=92\]                            

    B) \[{{T}^{2}}{{\left[ \frac{\delta (G/T)}{\delta T} \right]}_{p}}\]

    C) \[-{{T}^{2}}{{\left[ \frac{\delta (G/T)}{\delta T} \right]}_{p}}\]                   

    D)  None of the above

    Correct Answer: C

    Solution :

    Let\[I=\int_{1}^{4}{{{\log }_{e}}[x]}dx\] \[=\int_{1}^{2}{{{\log }_{e}}1}dx+\int_{2}^{3}{{{\log }_{e}}}2dx+\int_{3}^{4}{{{\log }_{e}}3dx}\] \[={{\log }_{e}}2+{{\log }_{e}}3={{\log }_{e}}6\]
