Keq=[CO] [H2O] / [CO2] [ H2] = 4.40 = X2 / (0.214-X)2. For this equilibrium, Keq=4.40, which is certainly NOT less than initial concentrations, so the assumption that X will be small is no longer valid. However, there is another algebraic simplification: Take the square root of both sides of the equation above, to give. 2.098 = X / (0.214-X)

We know the value of Keq (55.6 in this case), so we plug the values from the table into the Keq expression and solve for x! H2 + I2 2HI. Plugging in values for equilibrium concentrations from the [E] row of the ICE Table: This looks an awful lot like a quadratic, but relax! (we don't use those in …
