In the following reaction; x A → y B log_10[-(d [ A ])/dt]= log_10[(d [ B ])/dt]+0.3010 'A' and 'B' respectively can be:

In the following reaction; $\displaystyle x \mathrm{~A} \rightarrow y \mathrm{~B}$ $$\log _{10}\left[-\frac{\mathrm{d}[\mathrm{~A}]}{\mathrm{dt}}\right]=\log _{10}\left[\frac{\mathrm{~d}[\mathrm{~B}]}{\mathrm{dt}}\right]+0.3010 $$ 'A' and 'B' respectively can be :
