Is the unit for equilibrium constant for reaction 2H₂O → H₃O⁺ + OH⁻?

Explanation

The unit of an equilibrium constant depends on the difference in the number of moles between products and reactants (Δn).

In this case, since there are 2 moles of reactants (H₂O) and 2 moles of products (H₃O⁺ + OH⁻), Δn is 0, resulting in no unit for the equilibrium constant.
