Write the equilibrium constant expression for this reaction:NH3(aq)+H+(aq) → NH+4(aq)

The equilibrium constant expression for the reaction NH3(aq) + H+(aq) → NH4+(aq) is written as:

K = [NH4+] / ([NH3] [H+])

Where:

• K is the equilibrium constant
• [NH4+] is the molar concentration of NH4+ at equilibrium
• [NH3] is the molar concentration of NH3 at equilibrium
• [H+] is the molar concentration of H+ at equilibrium

The brackets denote the molar concentration of the species at equilibrium. The reactants are in the denominator and the products are in the numerator.
