Chemical equilibrium worksheet A (answer key)
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Keq=4.40, which is certainly NOT less than initial concentrations, so the assumption that X will be small is no longer valid.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.
