(a) At 800 K the equilibrium constant for \(\mathrm{I}_{2}(\mathrm{g}) \rightleftharpoons 2 \mathrm{I}(\mathrm{g})\) is \(K_{c}=3.1 \times 10^{-5}\). If an equilibrium mixture in a 10.0-L vessel contains \(2.67 \times 10^{-2} \mathrm{g}\) of I(g), how many grams of \(\mathrm{I}_{2}\) are in the mixture? (b) For \(2 \mathrm{SO}_{2}(g)+\mathrm{O}_{2}(g) \rightleftharpoons 2 \mathrm{SO}_{3}(g)\), \(K_{p}=3.0 \times 10^{4}\) at 700 K. In a 2.00-L vessel the equilibrium mixture contains 1.17 g of SO3 and 0.105 g of \(\mathrm{O}_{2}\). How many grams of \(\mathrm{SO}_{2}\) are in the vessel?
