Achemist wants to find kc for the following reaction at 709 k: 2nh3(g) + 3 i2 (g) > 6hi(g) + n2(g)
kc =

422455.41

Explanation:

Corrected from source,

Given that:-

The equilibrium constant for the reverse reaction will be the reciprocal of the initial reaction.

The value of equilibrium constant the reaction

is:

If the equation is multiplied by a factor of '3', the equilibrium constant of the reverse reaction will be the cube of the equilibrium constant  of initial reaction.

The value of equilibrium constant the reaction

is:

Adding both the reactions we get the final reaction. So, the equilibrium constants must be multiplied.

The value of equilibrium constant the reaction

is:

 = 422455.41
