Equilibrium Calculations - 2 1) Chemists have carried out studies of the high-temperature reaction of sulfur dioxide with oxygen in which the reactor initially contained 0.0076 M SO 2 , 0.0036M O 2 and no SO 3 . After equilibrium was achieved, the SO 2 concentration decreased to 0.0032 M. Complete the iCE table and use this information to calculate the K eq at this temperature for 2SO 2(g) + O 2(g) 2 SO 3(g) 2) A 5.0-L reaction flask initially contains 0.030 mol of sulfuryl chloride at 177 ºC. Sulfur dioxide and chlorine form: SO 2 Cl 2(g) SO 2(g) + Cl 2(g) After equilibrium is established, analysis shows that 0.0010 mol of SO 2 Cl 2(g) remains. Complete the iCE table and use this information to calculate the K eq for this reaction. 3) If 1.0 mol each of SO 2 and NO 2 are sealed in a 1.0-L flask at 1500 K, they react to form SO 3 and NO SO 2(g) + NO 2(g) SO 3(g) + NO (g) . K eq is 1.98. Complete the iCE table and use this information to write the expression for the equilibrium constant in polynomial form. 4)
