What is Keg for the reaction N2 + 3H2 = 2NH2 if the equilibrium

concentrations are [NH3] = 2 M [N2] = 3 M, and [H2] = 1 M?

O A. Keq = 0.67

O B. Keq = 0.75

O C. Keq = 1.33

O D. Keq = 1.5

The equilibrium constant for the given reaction is 1.33

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:

The expression of for above equation follows:

Putting values in above equation, we get:

Hence, the equilibrium constant for the given reaction is 1.33

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
