Harlamova29_29 [7]

<u>Answer:</u> The equilibrium constant for the given equation is 0.0315

<u>Explanation:</u>

We are given:

Total pressure in the container = 0.596 atm

The given chemical equation follows:

              N_2H_6CO_2(s)\rightleftharpoons 2NH_3(g)+CO_2(g)

<u>Initial:</u>              -

<u>At eqllm:</u>         -                   2x           x

Evaluating the value of 'x'  

\Rightarrow (x+2x)=0.596\\\\x=0.199

The expression of K_p for above equation follows:

K_p=p_{CO_2}\times (p_{NH_3})^2

The partial pressure of pure solids and pure liquids are taken as 1 in the equilibrium constant expression.

Putting values in above expression, we get:

K_p=(0.199)\times (2\times 0.199)^2\\\\K_p=0.0315

Hence, the equilibrium constant for the given equation is 0.0315
