Answer: The equilibrium constant for the given reaction is 1.33

Step-by-step explanation:

We are given:

Equilibrium concentration of ammonia = 2 M

Equilibrium concentration of nitrogen gas = 3 M

Equilibrium concentration of hydrogen gas = 1 M

For the given chemical equation:


N_2+3H_2\rightleftharpoons 2NH_3

The expression of
K_(eq) for above equation follows:


K_(eq)=([NH_3]^2)/([N_2][H_3]^3)

Putting values in above equation, we get:


K_(eq)=((2)^2)/(3* (1)^3)\\\\K_(eq)=1.33

Hence, the equilibrium constant for the given reaction is 1.33
