K = 0.15 at 25 °C 16). For the reaction: N,O4(g) = We initially mixed 3 M of N2O4 gas with 1 M of NO2 gas in a 1.0 L sealed flak and allowed the reaction to reach equilibrium. When equilibrium is established what are the terms representing each of the concentration of the gases? Or, another word, what are the terms at the Line E? 2NO2(g) N2O4(g) = 2NO2(g) 1 + 2x N2O4(g) = 2NO2(g) 1- 2x N2O4(g) = 2NO2(g) 1- 2x а. b. Line E: 3- x N2O4(g) = 2NO2(g) 1 + x Line E: 3+x d. Line E: 3+ 2x с. Line E: 3 - x e. none of the above

[References] The equilibrium constant for the reaction PCl, 2 PC13 + Cl2 is 0.0245 at 250.°C. What molar concentration of PCl; would be present at equilibrium if the concentrations of PCI3 and Cl2 were both 0.161 M? Molar concentration of PCI3 = M

Consider the reaction, 2AB2(g) = A2(g) + 2B2(g), Kc = 0.263 at 25°C. The reaction begins with an unknown concentration of AB2 in the reaction flask. At equilibrium, the concentration of AB2 is found to be 0.00545 M. a) Complete the ICEE table below, b) Write the equilibrium expression and equation for this reaction (pay close attention to coefficients!), c) Calculate the equilibrium concentration of both products, and d) Calculate the initial concentration of AB2. You should confirm that your equilibrium concentrations will give the correct equilibrium constant when plugged into the expression. ICEE table I C E 2 AB₂(g) A₂(g) + 2 B₂(g)
