    When compared to \[\Delta {{G}^{o}}\] for the formation of \[A{{l}_{2}}{{O}_{3}}\], the \[\Delta {{G}^{o}}\] for the formation of \[C{{r}_{2}}{{O}_{3}}\] is

    A)  Higher        

    B)  lower

    C)  Same          

    D)  unpredicted

    Correct Answer: A

    Solution :

    Between \[A{{l}_{2}}{{O}_{3}}\] and \[C{{r}_{2}}{{O}_{3}},A{{l}_{2}}{{O}_{3}}\],  is more stable, so its ease of formation is high i.e., \[\Delta {{G}^{o}}\] is negative or less than that of \[C{{r}_{2}}{{O}_{3}}\]. Hence, \[\Delta {{G}^{o}}\] of \[C{{r}_{2}}{{O}_{3}}>\Delta {{G}^{o}}\] of \[A{{l}_{2}}{{O}_{3}}\]
