Carbon monoxide gas, CO(g), is a primary starting material in the synthesis of many organic compounds, including methanol, CH3OH(l). At 20000C, K is 6.40x10-7 for the decomposition of carbon dioxide gas, CO2(g), into carbon monoxide and oxygen, O2(g). Calculate the concentrations of all entities at equilibrium if 0.250mol of CO2(g) is placed in a 1.000L closed container heated to 20000C.
2CO2(g) → 2CO(g) + O2(g)
= 6.4 × 107 × 0.250/1000 × 2000
= 8 mol/L
