6. For the system, if we start with 0.010 mol/L of H2 and 12 and 0.096 mol/L of Hl, what are their concentrations at equilibrium given that Keq - 0.0161 Answer: [Hlleq-0.093 M, [H2leq-U2leq 0.012 M) 2H1(g) H2 (g) 12 (g) ââ + At 650°C, the reaction below has a Kea value of o.771. If2.00 mol of both hydrogen and carbon dioxide are placed in a 4.00 L container and allowed to react, what will be the equilibrium concentrations of all four gases? 7. (Answer: [Coleq-H20leq-0.234 M, [H2leq=[CO21eq-0.266 M) Answer: [COleq [H2Oleq-0.234 M, [H2leq- ICO2leq- 0.266 M) H2 (g) CO2 (g) CO (g) H2O (g) + + Carbonyl bromide, COBr2, can be formed by reacting Co with Br2. A mixture of 0.400 mol CO, 0.300 mol Br2, and 0.0200 mol COBr2 is sealed in a 5.00L flask. Calculate equilibrium concentrations for all gases, given that the Keq= 0.680. 8. (Answer: [Coleg = 0.0807 M, [ Brleq-0.0607 M, [COBr21eq-0.0033 M) CO (g) Br2 (g) COB"2 (g) + ââ
