For problem 35 at the end of chapter 5, how do you know the balance to Quetion between the reactant A and the two products B and C?

If you look at the graph provided in the question, you will be able to determine the amount of A consumed and the amount of B and C formed in reaction in establishing equilibrium. If you set up an ICE table and plug in the initial and equilibrium partial pressure values, you can determine the change (the “C” in ICE) which will show a ratio between all three molecules. Through this, you can determine whether the change for each molecule was — -x, -2x, +x, +2x, etc. — and the coefficient in front of the “x” will tell you the coefficient of the molecule in reaction.

Got it! Making an ice chart and laying out all the information really helped me understand how to balance the equation. Thanks so much !
