What are competive electron transfer reaction ? Give example.

Explanation

These are the reaction in which redox reactions take place in different vessels and it is an indirect redox reaction. There is a competition for the release of electrons among different metals.
Eg : Zn releases electrons to Cu and Cu releases electrons to silver and SO on
`Zn_((s))+Cu^(2+) to Zn_((aq)))^(2+)+Cu_((s))` (Here Zn oxidised `Cu^(2+)-` reduced)
`Cu_((g))+2Ag^(+)to Cu_((aq))^(2+)+2Ag_((g))` (Here Cu oxidised `Ag^(+)-` reduced)
