Topical Questions

These questions are keyed to the major topics in the chapter. Usually a question that is answered at the back of this book is paired with a similar one that is not.

Consider the equilibrium at 25 °C

Suppose that 0.15 mol SO₃(g), 0.015 mol SO₂(g), and 0.0075 mol O₂(g) are placed into a 10.0-L flask at 25 °C and the flask is sealed.

(a) Is the system at equilibrium?

(b) If the system is not at equilibrium, in which direction must the reaction proceed to reach equilibrium? Explain your answer.
