Question

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

Answer 1

`k = ([NH_3][H^+])/([NH_4^+])`

Step-by-step 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:

`k = ([C]^c[D]^d)/([A]^a[B]^b)`

For the reaction:

NH₄⁺(aq) ⇄ NH₃(aq) + H⁺(aq)

The equilibrium constant is:

`k = ([NH_3][H^+])/([NH_4^+])`
