### Homework Question 11.7

In question 11.7, it gives you four different flasks containing different concentrations of both products and the reactants. Can someone explain how you would decipher which flask is at equilibrium? Thank you so much!

Notice that you can see which molecules have decayed within the flask. Start with counting out how many molecules have split apart!

Basically, when the amount of diatomic molecules stays the same between flasks that's when equilibrium has been reached. I have another question regarding 11.7. For the part that asks you to calculate K but only gives you the partial pressure of the diatomic molecules, how do you figure out the pressure for the disassociated particles?

The answer is flask 3 but I counted the the number of molecules that have split apart and there are 12 of these in both flasks 3 and 4. So why is flask 3 the answer?

You can determine that equilibrium was reached in flask 3 because there is no further disassociation from flask 3 to flask 4.
