Question

10

The reaction in which ammonia is formed is N2(g) + 3H2(g) + 2NH3(). At equilibrium, a
1-L flask contains 0.15 mol H. 0.25 mol N, and 0.10 mol NH. Calculate K., for the reaction.

Answer 1

The equilibrium constant (K) : 11.85

Further explanation

Given

Reaction

N₂(g) + 3H₂(g) ⇒ 2NH₃(g)

Required

K(equilibrium constant)

Solution

The equilibrium constant (K) is the value of the concentration product in the equilibrium

The equilibrium constant based on concentration (K) in a reaction

pA + qB -----> mC + nD

`\tt K=([C]^m[D]^n)/([A]^p[B]^q)`

For the reaction above :

`\tt K=([NH_3]^2)/([N_2][H_2]^3)\\\\K=(0.1^2)/(0.25* 0.15^3)\\\\K=11.85`
