In a certain reaction 1.5 mol of CO and 1.5 mol of H2O are placed in a 2,0 dm3 sealed vessel. Equilibrium is established at a temperature of 1 000 C. The equilibrium reaction equation is
CO(g) + H2O(g) = CO2(g) + H2(g)
The value of Kc for this reaction is 0,63. Calculate the concetration of CO2 present at equilibriumin the reaction mixture.
