1) At 1 atm and 25 °C, No, with an initial concentration of 1.00 M is 3.3 x 10-3% decomposed into NO and O2. Calculate the value of the equilibrium constant for the reaction 2NO2(g) ââ 2NO(g) + O2(g) (20 points) 2) Analysis of the gases in a sealed reaction vessel containing NH3, N2, ad H2 at equilibrium at 400°C established the concentration of N2 to be 1.2 Mand the concentration of H2 to be 0.24 M N2(g)+3H2(g) ââ 2NH3(g) Calculate the equilibrium molar concentration of NH3. (20 Points) Kc= 0.5 at 400 C 3) Assume that the change in concentration of N204 is small enough to be neglected in the following problem. (20 Points) (a) Calculate the equilibrium concentration of both species in 1.00 L of a solution prepared from 0.129 mol of N20, with chloroform as the solvent. N204(g) â 2NO2(g) Kc = 1.07 x 10~5 in Chloroform (b) Show that the change is small enough to be neglected 4) What are all concentrations after a mixture that contains [H2O] 1.00 M comes to equilibrium at 25 °C? (20 points) H2O(g) + Cl2ãââ 2HOCI(g) 1.00 Mand [CLO]= Kc = 0.09
