**Experiment Summary: Equilibrium Constant Calculation**

A student conducted the following reaction in the laboratory at 448 K:

\[ \text{PCl}_5(g) \rightleftharpoons \text{PCl}_3(g) + \text{Cl}_2(g) \]

**Experimental Details:**

- The student introduced 1.05 moles of \(\text{PCl}_5(g)\) into a 1.00-liter container.
- The equilibrium concentration of \(\text{Cl}_2(g)\) was 0.0343 M.

**Objective:**

Calculate the equilibrium constant, \( K_c \), for this reaction.

**Calculation Required:**

\[ K_c = \, \] [Place your calculated equilibrium constant here]

This task involves determining \( K_c \) using the initial conditions and the equilibrium concentration provided.
