Question 4 (1 point) At high temperatures, carbon dioxide gas, CO2 (), decomposes into carbon monoxide gas, CO (E), and oxygen gas, O2 (g). The concentrations of the gases at equilibrium are (CO2) - 1.2 mol/L, [CO] -0.35 mol/L, and [02] = 0.15 mol/L. Determine Keq at the equilibrium temperature, 0.044 78.37 0.013 6.56*103
