Ch 11 #7c

The SSM uses the initial pressure value for both the numerator and denominator; how? Should we assume that the pressure is constant?

I didn't understand how to answer this part of the question either.

"11.7: The following flasks show the dissociation of a diatomic molecule, X2, over time. (a) Which flask represents the point in time at which the reaction has reached equilibrium?
(b) What percentage of the X2 molecules have decomposed at equilibrium? (c) Assuming that the initial pressure of X2 was 0.10 bar, calculate the value of K for the decomposition."

How do we calculate the value of K?
