    The chemical reaction, \[MgSi{{O}_{3}}\], proceeds as follows: \[CaSi{{O}_{3}}\] \[N{{a}_{2}}C{{O}_{3}}\xrightarrow{s{{o}_{2}}}A\xrightarrow{Na{{ & }_{2}}C{{O}_{3}}}B\xrightarrow[\Delta ]{Elemental}\] The rate law expression should be

    A) \[C\xrightarrow{{{I}_{2}}}D\]                     

    B) \[r={{k}^{1}}{{[{{O}_{3}}]}^{2}}{{[{{O}_{2}}]}^{-1}}\]

    C) \[\text{N}{{\text{a}}_{\text{2}}}{{\text{S}}_{2}}{{\text{O}}_{3}}\]           

    D) unpredictable

    Correct Answer: B
