What is e.m.f. of the cell, when the cell reaction attains equilibrium ?

calculate the e.m.f of the cell in which the following reaction takes place: Ni(s) +2Ag^(+) (0.002M)rarrNi^(2+) (0.160 M)+2Ag(s) Given that E_(cell)^o=1.05V

The e.m.f of the following galvanic cell:

Define electrochemical cell, emf reaction.

What is e.m.f. of a cell ? On what factors does its value depend ?

The e.m.f. of the cell used in the main circuit of the potentiomter should be more than the potential diference to be measured. Why?

Write the half cell reaction and the overall cell reaction for the electrochemical cell: Zn|Zn^(2+)(1.0M)||Pb^(2+)(1.0M)|Pb Calculate the standard e.m.f. for the cell if standard electrode potentials for Pb^(2+)|Pb and Zn^(2+)|Zn electrodes are -0.126V and -0.763V respectively.
