$(A)\,\xrightarrow[{excess}]{{Me\, - \,I}}\,(C)\,\xrightarrow[{(ii)\,\,{H^ + }}]{{(i)\,\,NaN{H_2}}}(D)$
In the light of the above statements, choose the correct answer from the options given below :
${\log _{10}}\,\left[ { - \frac{{d\left[ A \right]}}{{dt}}} \right] = {\log _{10}}\,\left[ {\frac{{d\left[ B \right]}}{{dt}}} \right] + 0.3010$
$‘A’$ and $‘B’$ respectively can be
