Based on the arrangement of metals in the reactivity series, iron is placed above tin and below zinc, this means that iron is more reactive than tin but less reactive than zinc. This means that iron would displace tin ions in a solution whereas zinc would displace iron ions in a solution.
The reactivity of metals is due to the stability of metals in their electron configurations as atoms and as ions.
