Question
**Chemistry Equilibrium Problem**

Consider the following reaction where \( K_c = 34.5 \) at 1150 K.

\[ 2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g) \]

A reaction mixture was found to contain \( 2.24 \times 10^{-2} \) moles of \( SO_2(g) \), \( 4.12 \times 10^{-2} \) moles of \( O_2(g) \), and \( 4.40 \times 10^{-2} \) moles of \( SO_3(g) \) in a 1.00 liter container.

**Questions:**
1. Is the reaction at equilibrium?
2. If not, what direction must it run in order to reach equilibrium?

**Calculation:**
The reaction quotient, \( Q_c \), equals:

\[ Q_c = \frac{{[SO_3]^2}}{{[SO_2]^2[O_2]}} \]

where \([SO_2] = 2.24 \times 10^{-2}\), \([O_2] = 4.12 \times 10^{-2}\), and \([SO_3] = 4.40 \times 10^{-2}\).

**Determine the Reaction Direction:**

The reaction:

- A. must run in the forward direction to reach equilibrium.
- B. must run in the reverse direction to reach equilibrium.
- C. is at equilibrium.
