If the initial concentrations of nh3(g) and h2s(g) are 2.0 m, what is the equilibrium concentration of nh3(g)?

The question is incomplete, here is the complete question:

at 900 K for the reaction

If the initial concentrations of and are 2.0 M, what is the equilibrium  concentration of ?

The equilibrium concentration of ammonia is 0.32 M

Explanation:

We are given:

Initial concentration of ammonia = 2.0 M

Initial concentration of hydrogen sulfide = 2.0 M

For the given chemical reaction:

Initial:        2.0      2.0

At eqllm:    2.0-x     2.0-x            x

The expression of for above equation follows:

The concentration of pure solids and pure liquids are taken as 1

We are given:

Putting values in above equation, we get:

Neglecting the value of x = 1.68 because equilibrium concentration cannot be greater than initial concentration

So, equilibrium concentration of ammonia = 2 - x = (2 - 1.68) = 0.32 M

Hence, the equilibrium concentration of ammonia is 0.32 M

the correct answer to this question is 2
