$\frac{2.303 \times 3 \log 2}{10}$

(A) For a first order reaction,the rate constant $k$ is given by the formula:$k = \frac{2.303}{t} \log_{10} \frac{a}{a-x}$Given $t = 10 \, \text{min}$ and $\frac{a}{a-x} = 8$.Substituting these values into the equation:$k = \frac{2.303}{10} \log_{10} 8$Since $8 = 2^3$,we can write $\log_{10} 8 = \log_{10} 2^3 = 3 \log_{10} 2$.Therefore,$k = \frac{2.303 \times 3 \log 2}{10}$.
