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) (double arrow) to CO2(g0 + H2(g), which has an equilibrium constant Kc=4.24 at 800 K. Calculate the equilibrium concentrations of CO2, H2, and H2O at 800 K if only CO and H2O are present intially at concentrations of .119M?
What is the second step in the scientific method? 1-to analyze the data, and create a theory to confirm the experimental observations 2- to analyze the data, and propose a tentative hypothesis to explain the experimental observations.
