No reaction.
Reason: Cl− is just a spectator ion and Fe(s) cannot reduce Na+ to Na(s). From the activity series (or standard potentials) Na is more reactive than Fe, so Fe cannot displace Na+. Using standard reduction potentials: E°cell = E°(Na+/Na) − E°(Fe2+/Fe) ≈ −2.71 − (−0.44) = −2.27 V (negative), so the displacement is non‑spontaneous. Also metallic sodium would not be produced in water (it would react violently with water).
