Answer:
[tex]k = \frac{[NH_3][H^+]}{[NH_4^+]}[/tex]
Explanation:
The equilibrium constant of a reaction is defined as the ratio of the concentrations of products over concentrations of reactants powered to its coefficients. For the reaction:
aA + bB ⇄ cC + dD
The equilibrium constant, k, is written as:
[tex]k = \frac{[C]^c[D]^d}{[A]^a[B]^b}[/tex]
For the reaction:
NH₄⁺(aq) ⇄ NH₃(aq) + H⁺(aq)
The equilibrium constant is:
[tex]k = \frac{[NH_3][H^+]}{[NH_4^+]}[/tex]
