Write the equilibrium constant expression for this reaction:H3PO4(aq) → 3H+(aq)+PO3−4(aq)
Question
Write the equilibrium constant expression for this reaction:H3PO4(aq) → 3H+(aq)+PO3−4(aq)
Solution
The equilibrium constant expression for the given reaction is written as follows:
K = [H+]^3 [PO4^3-] / [H3PO4]
Where:
- K is the equilibrium constant.
- [H+], [PO4^3-], and [H3PO4] are the molar concentrations of H+, PO4^3-, and H3PO4 respectively at equilibrium.
- The exponents on the concentrations (in this case, 3 on [H+]) correspond to their stoichiometric coefficients in the balanced chemical equation.
