No reaction.
Reason: Cu(s) + Fe2+(aq) -> Cu2+(aq) + Fe(s) would require copper to be oxidized and iron(II) reduced. Standard potentials: Cu2+/Cu = +0.34 V, Fe2+/Fe = −0.44 V. The cell potential for that displacement is negative (E°cell = −0.78 V), so the reaction is not spontaneous. In the reactivity series, Fe is above Cu, so Cu cannot displace Fe2+ from solution.
