The reaction that occurs in a breath analyser, a device used to determine the alcohol level in a persons bloods stream is
\[
\begin{array}{l}
2 \mathrm{~K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}+8 \mathrm{H}_{2} \mathrm{SO}_{4}+3 \mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O} \rightarrow 2 \mathrm{Cr}_{2}\left(\mathrm{SO}_{4}\right)_{3}+3 \mathrm{C}_{2} \mathrm{H}_{4} \mathrm{O}_{2} \\
+2 \mathrm{~K}_{2} \mathrm{SO}_{4}+11 \mathrm{H}_{2} \mathrm{O} \\
\end{array}
\]
If the rate of appearance of \( \mathrm{Cr}_{2}(\mathrm{SO})_{4} \) is \( 2.67 \mathrm{~mol} \mathrm{~min}^{-1} \) at a particular time, the rate of disappearance of \( \mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O} \) at the same time is \( \operatorname{mol~} \mathrm{min}^{-1} \) (Nearest integer)
