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

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell
