Chapter 14.7, Problem 14P

A closed system reactor initially contains two moles of SO₂ and two moles of O₂, and the following reaction is carried out until it reaches equilibrium:

2SO₂(g) + O₂(g) ↔ 2SO₃(g)

1. A. For a constant reaction pressure of 1 bar, plot the final number of moles of SO₃ as a function of temperature over the range 300 to 1000 K using the shortcut van ’t Hoff equation.
2. B. Repeat part A for pressures of 2, 5, 10, and 25 bar. Assume the system is an ideal mixture of real gases.
