Question 18

The contact process involves the homogeneous gaseous equilibrium shown below:

2SO2(g)+O2(g)⇌2SO3(g) 2\text{SO}_2(\text{g}) + \text{O}_2(\text{g}) \rightleftharpoons 2\text{SO}_3(\text{g}) 2SO2​(g)+O2​(g)⇌2SO3​(g)

In a test mixture, 4.00 mol of sulfur dioxide are mixed with 3.00 mol of oxygen. At equilibrium, the total amount of the three gases present in the mixture is 5.80 mol.

What is the mole fraction of sulfur trioxide at equilibrium?
