Write the iCe table for the reaction and initial concentrations given in

(a) Exercise 14.31.

(b) Exercise 14.32.

Exercise 14.31

A 20.0-L flask contains 1.0 mol PCl₅(g) and 2.0 mol each of PCl₃(g) and Cl₂(g). K_c at 425 °C is 4.0 for

Calculate the reaction quotient, Q, and draw a number line with Q and K_c in the appropriate places. In which direction will the reaction proceed?

Exercise 14.32

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.

Is the system at equilibrium?

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