1.	What are competive electron transfer reaction ? Give example.
Answer» Solution :These are the reactions 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. Example: Zn releases electrons to Cu and Cu releases electrons to silver and so on `Zn_((s))+Cu^(2+)rarrZn_(aq)^(2+)+Cu_((s))` (Here Zn - oxidised : `Cu^(2+)` - REDUCED) `Cu_((s))+2Ag^(+) rarr Cu_(aq)^(2+)+2AG_((s))` (Here Cu - oxidised, `Ag^(+)` - reduced )
