6. A study of the following system was carried out. 4 NH3(g) + 7 Oz(g) 2 N204(g) + 6 H2O(g) The reaction was prepared with (NH3) = [O2) = 3.60 M as the only components, initially. At equilibrium, (N2O4) = 0.60 M was measured. Calculate the value of the equilibrium constant, Kc, for the reaction. 7. Consider the following reaction: 2C10(g) SCl2(g) + O2(g) K = 6.4 x 103 In an experiment, 0.100 mol of ClO(g), 1.00 mol of O2(g), and 0.0100 mol of Cl2(g) were added to a 4.00 L reaction vessel. Calculate all equilibrium concentrations (add another piece of paper for space, if needed).
