solving 11.7

Postby Sammy Thatipelli 1B » Mon Nov 20, 2017 5:24 pm

How do you know which flask represents equilibrium in this question? For equilibrium, does it occur when the number of double molecules equal the number of single molecules in the flask? I am having a hard time understanding how the diagram shows equilibrium.

At equilibrium, the concentrations of reactants and products are constant, so they don't have to necessarily be equal. In this case, the concentration of "single" and "double" molecules do not change from the third to the fourth flask because the number of each remains constant. Therefore, the third flask is where the reaction has reached equilibrium.

It's basically just counting molecules in the flasks. You'll also need that for part B of the question where you find percentage decomposed.
