When solid ammonium carbamate sublimes, it dissociates completely into ammonia and carbon dioxide according to the following equation: At 50 °C, experiment shows that the total pressure of the gases in equilibrium with the solid is 0.596 atm. What is the equilibrium constant, ?

The equilibrium constant for the given equation is 0.0315

Explanation:

We are given:

Total pressure in the container = 0.596 atm

The given chemical equation follows:

Initial:              -

At eqllm:         -                   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

it is b that is the answer.
