Comm. marks are awarded for a) accurate balanced chemical equations, including states. b) work being well organized, shows all steps to calculations, and uses proper set up and formatting, c) correct units and significant digits reported. 1. At 1200.0C, the value of Keq for the formation of hydrogen iodide gas is 2.51 x 104. Determine the equilibrium concentrations of all reactants and products if 0.250 mol/L of iodine gas, and 0.250 mol/L of hydrogen gas react to form hydrogen iodide gas. [6 marks T + 3 marks C] 2. At 2000.0C, the Keq for the decomposition of carbon dioxide gas to carbon monoxide and oxygen gases is 6.40 x 10-7. Determine the equilibrium concentrations of all reactants and products when 1.00 mol of carbon dioxide gas is placed in a 1.00 L vessel. [7 marks T + 3 marks C]
