Please explain me how to identify or write the net reaction involved in the redox reaction while solving the numericals based on Faraday's laws?

Right individual reactions with free elecrons. Then multiply equations and add them to get rid of electrons. or example if half reactions are
Zn--> Zn2+ + 2e-
Ag+ + e- --> Ag
Then multiply second equation by 2. And add. The two electrons will cancel each other and net reaction becomes
Zn + 2Ag+ --> Zn2+ + 2Ag
