10. Sulfur trioxide decomposes according to the reaction: 2 SO3 (g) = 2 SO2 (g) + O2 (g) In an equilibrium mixture at 1000 K you measure [SO3] =0.41 M, [S02] = 0.032 M, and the [O2] = 0.59 M. What is the value of Kc for this reaction at this temperature? A) 3.6 X 103 B) 1.1 X 101 C) 2.2 X 10? D) 4.6 X 104 11. At a certain temperature, the following reaction has a Kc value of 4.0 X 104: N2 (g) + O2 (g) = 2 NO (g) At equilibrium, you find [N2] = 0.25 M and the [O2] = 0.33 M. What is the [NO]? A) 6.8 X 103 B) 5.7 X 103 C) 1.7 X 105 D) 3.3 X 105
