Reaction $\mathrm{A} \rightarrow \mathrm{B}$ follows first-order elementary kinetics and the reaction rate constant for $\text{A}$ is $0.01$ per min.
The time taken to reduce the concentration of $\text{A}$ from $100$ $\text{M}$ to $10$ $\text{M}$ in a batch reactor is $\_\_\_\_$ $\min$ (rounded off to one decimal place).
