Question 57

Multiple Choice

A study of the system, 4 NH3(g) + 7 O2(g) A study of the system, 4 NH<sub>3</sub>(g) + 7 O<sub>2</sub>(g)    2 N<sub>2</sub>O<sub>4</sub>(g) + 6 H<sub>2</sub>O(g) , was carried out. A system was prepared with [NH<sub>3</sub>] = [O<sub>2</sub>] = 3.60 M as the only components initially. At equilibrium, [N<sub>2</sub>O<sub>4</sub>] is 0.60 M. Calculate the value of the equilibrium constant, K<sub>c</sub>, for the reaction.Hint: Organize your information using an ICE table, then use the equilibrium N<sub>2</sub>O<sub>4</sub> concentration to find the concentrations of all reactants and products to find K<sub>c</sub>. A) 8.1 B) 0.0000093 C) 0.30 D) 0.022 E) 3.3 2 N2O4(g) + 6 H2O(g) , was carried out. A system was prepared with [NH3] = [O2] = 3.60 M as the only components initially. At equilibrium, [N2O4] is 0.60 M. Calculate the value of the equilibrium constant, Kc, for the reaction.Hint: Organize your information using an ICE table, then use the equilibrium N2O4 concentration to find the concentrations of all reactants and products to find Kc.
