At $\mathrm{T}(\mathrm{K}), \mathrm{K}_{\mathrm{c}}$ value of $\mathrm{AO}_2(\mathrm{~g})+\mathrm{BO}_2(\mathrm{~g}) \rightleftharpoons \mathrm{AO}_3(\mathrm{~g})+\mathrm{BO}(\mathrm{g})$ 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 $\mathrm{T}(\mathrm{K})$. Identify the correct statements about this equilibrium. I) Total number of moles at equilibrium is 4 II) At equilibrium, the ratio of moles of $\mathrm{AO}_2$ and $\mathrm{AO}_3$ is $1: 4$ III) Total number of moles of $\mathrm{AO}_2$ and $\mathrm{BO}_2$ at equilibrium is 0.8
