41. The standard reduction potential of Pb and Znelectrodes are -0.126

1.	41. The standard reduction potential of Pb and Znelectrodes are -0.126 and -0.763 voltsrespectively. The e.m.f. of the cellZn \| Zn2+ (0.1 M) \|\| Pb2+ (1 M)\| Pb is(1) 0.637 V(2) < 0.637 V(3) > 0.637 V (4) 0.889
Answer» welcome to the CONCEPT of emf in this question concentration is ALSO GIVEN so we use nerset equation . E ° cell = 0.736-0.1236 = 0.61 Q= 10^-1 and n =2 now by nernst equation E cell = 0.64

Answer»

welcome to the CONCEPT of emf

in this question concentration is ALSO GIVEN so we use nerset equation .

E ° cell = 0.736-0.1236 = 0.61

Q= 10^-1 and n =2

now by nernst equation

E cell = 0.64
