Why Is Water Eliminated From The Equilibrium Equation at Gerald Devries blog

Why Is Water Eliminated From The Equilibrium Equation. We can't increase the concentration of a pure liquid. If water is the solvent, it would be very normal to ignore the water which is produced or the water which might act as a reactant. The autoionization of liquid water produces \ (oh^−\) and \ (h_3o^+\) ions. Dehydration reactions are just elimination reactions where water is eliminated. Water is omitted from the equilibrium expression only if it is a solvent in that reaction because it is a pure liquid. The equation in the image shows how we can get an alkene. Usually when you have water in a reaction it is taken in excess, i.e in a much larger quantity compared to the other reactants. The reason we can leave water out of the equation is that with it being a very dilute solution, with a relatively huge number of water molecules present, any reaction of the. Because h 2 is a good reductant and o 2 is a good oxidant, this reaction has a very large equilibrium constant (k = 2.4 × 1047 at 500 k). In equations 6 through 10, you saw how the constant concentration of a solid (and the same argument would hold for a liquid) can be used to exclude it from the equilibrium constant.
