4. Sulfuric acid is an important industrial chemical thatis usually produced by a series of reactions. One ofthese involves an equilibrium between gaseous sulfurdioxide, oxygen, and sulfur trioxide.2 SO,(g) + O,(g) = 2 SO,(g)If 2.5 mol of sulfur dioxide gas and 2.0 mol ofoxygen gas are placed in a sealed 1.0 L containerand allowed to reach equilibrium, 0.75 mol of sulfurdioxide remains. Use an ICE table to determine theconcentration of the other gases at equilibrium. E
