1 Faraday electricity was passed through Cu2+(1.5 M,1 L)/Cu and 0.1 Faraday was passed through Ag+(0.2M,1 L)/Ag electrolytic cells. After this the two cells were connected as shown below to make an electrochemical cell. The emf of the cell thus formed at 298 K is-
Given: ECu2+/Cuo=0.34 V
EAg+/Ag0=0.8 V
F2.303RT=0.06 V
