The cell potential forZnZn2+(aq)Snx+Snis0.801Vat298 K. The reaction quotient for the above reaction is10-2. The number of electrons involved in the given electrochemical cell reaction is _____ .
(GivenEZn2+Zn0=-0.763 V,ESnx+|Sn0=+0.008 Vand2.303RTF=0.06 V)

Answer:
4
Solution:

E=E0-2.303RTnFlogQ

Here,

E=+0.801 VE0=ECathode-EAnodeBoth are SRP valuesE0=0.008--0.763

=+0.771 V

0.801=+0.771-0.06nlog10-2
