<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:

<u>Initial:</u> -
<u>At eqllm:</u> - 2x x
Evaluating the value of 'x'

The expression of
for above equation follows:

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:

Hence, the equilibrium constant for the given equation is 0.0315
