A reactor's feed is composed of water and carbon monoxide(CO) in an unknown proportion. Once the reaction occurs, the reactor's effluent that contains 3% mole H2, passes through a separator form which 2 currents exit. 1) the product's current contains 48% mole H2, 48% Mole Co2 and 4% mol CO. 2) the recirculation current is composed of H2O and CO, and the reirculation current joins the process' fresh feed(thta only contains CO and H2O) assume 100 moles of product's current...

The H2/CO ratio in mixtures of carbon monoxide and hydrogen (called synthesis gas) is increased by the water-gas shift reaction CO(g)+H2O(g)⇌CO2(g)+H2(g), which has an equilibrium constant Kc=4.24 at 800 K. Part A Calculate the equilibrium concentrations of CO2, H2, CO, and H2O at 800 K if only CO and H2O are present initially at concentrations of 0.132 M .
