Fuel engineers use the extent of the change from CO and H2O to CO2 and H2 to regulate the proportions of synthetic fuel mixtures. If 0.250 mol of CO and 0.250 mol of H20 are placed in a 125-mL flask at 900K, what is the composition of the equilibrium mixture? At this temperature, Kc is 1.56 for the equation CO(g) + H20(g) = CO2(g) + H2(g)
