At $\mathrm{T}(\mathrm{K}), \mathrm{K}_{\mathrm{c}}$ value for $\mathrm{AO}_2(\mathrm{~g})+\mathrm{BO}_2(\mathrm{~g}) \rightleftharpoons \mathrm{AO}_3(\mathrm{~g})+\mathrm{BO}(\mathrm{g})$ is 16. In a closed 1 L flask, one mole each of $\mathrm{AO}_2, \mathrm{BO}_2, \mathrm{AO}_3$ and BO are taken and heated to $\mathrm{T}(\mathrm{K})$. What is the concentration (in $\mathrm{mol} \mathrm{L}^{-1}$ ) of $\mathrm{AO}_3$ at equilibrium?

• A

  0.4
• B

  0.6
• Correct answer
  C

  1.6
• D

  1.4

Hence, the correct answer is option: 'C'.
