................CO2(g) + H2(g) ↔ CO(g) + H2O(g)
initial.........0.1.............0.1..........0.............0
Change.......-x...............-x...........x.............x
Equilibrium..0.1-x.......0.1-x..........x.............x
Kc = (CO)(H2O)/(CO2)(H2) = 0.64
Plug in the values for Kc, and from the Eline of the ICE table, solve for x, then evaluate of the four terms in the E line.
Post your work if you get stuck.
Consider the reaction: CO2(g) + H2(g) ↔ CO(g) + H2O(g), for which Kc = 0.64 at 900 K. If the initial CO2 and of H2 are each 0.100 M, what will be the equilibrium concentrations of each species after the reaction reaches equilibrium?
