- The reaction is not feasible because Copper cannot replace Lead. - Lead is more reactive than Copper in the reactivity series. - The reactivity series is as follows:
K>Na>Ca>Mg>Al>C>Zn>Fe>Sn>Pb>H>Cu>Ag>Au>Pt.
- Potassium is the most reactive and can replace every other element in the series. - The other reactions are an example of the Displacement reaction. - In a Displacement reaction, a more reactive element displaces a less reactive element from its compound.
