Chapter 14, Problem 14.21QP

A mixture initially consisting of 2 mol CO and 2 mol H₂ comes to equilibrium with methanol, CH₃OH, as the product:

$\text{CO}(g)+2{\text{H}}_2(g)\stackrel{}{\rightleftharpoons }{\text{CH}}_3\text{OH}(g)$

At equilibrium, the mixture will contain which of the following?

1. a less than 1 mol CH₃OH
2. b 1 mol CH₃OH
3. c more than 1 mol CH₃OH but less than 2 mol
4. d 2 mol CH₃OH
5. e more than 2 mol CH₃OH
