Solution: The phase diagram for SO2 is shown here.Calculate the equilibrium constant for this reaction at 100 oC.

Problem

The phase diagram for SO2 is shown here.
The x axis is temperature in degrees C, ranging from negative 100 to 300 with intervals of 100. The y axis is pressure in atmospheres, ranging from 10 superscript -1 to 10 superscript 2 in log scale. Above the vapor pressure curve the phase is liquid, Below and to the right of the vapor pressure curve the phase is gaseous. The super critical fluid phase is to the right of the critical point and above the gas phase.

Calculate the equilibrium constant for this reaction at 100 oC.

Solution

We are being asked the equilibrium constant for the reaction at 100 oC.

The x axis is temperature in degrees C, ranging from negative 100 to 300 with intervals of 100. The y axis is pressure in atmospheres, ranging from 10 superscript -1 to 10 superscript 2 in log scale. Above the vapor pressure curve the phase is liquid, Below and to the right of the vapor pressure curve the phase is gaseous. The super critical fluid phase is to the right of the critical point and above the gas phase.

Recall: The equilibrium constant K is a ratio of products to reactants at a given temperature. It only deals with gaseous or aqueous compounds
