### Chemical Equilibrium Problem

**Consider the given reaction:**

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

- A reaction mixture at 780°C initially contains \([\text{CO}] = 0.500 \, \text{M}\) and \([\text{H}_2] = 1.00 \, \text{M}\) and no products.

- At equilibrium, the CO concentration is 0.15 M. What is the value of the equilibrium constant?

**Options:**
- ○ 26
- ○ 0.33
- ○ 33
- ○ 0.26

This exercise involves calculating the equilibrium constant \(K_c\) for the given reaction using initial concentrations and the change in concentration at equilibrium.
