If the $\mathrm{pH}$ of $0.10 \mathrm{M}$ monoacidic base at $298 \mathrm{~K}$ is 9.0 , the value of $\mathrm{K}_{\mathrm{b}}$ and $\mathrm{pK}_{\mathrm{b}}$ at the same temperature are respectively
  1. $1.0 \times 10^{-9}, 9.0$
  2. $1.0 \times 10^{-5}, 5.0$
  3. $1.0 \times 10^{-10}, 10.0$
  4. $1.0 \times 10^{-4}, 4.0$
