1.

when two half-cells of electrode potential of E_1 and E_2 are combined to form a half cell of electrode potential E_3 , then (when n_1,n_2 " and " n_3 are no. of electrons exchanged in first second and combined half-cells:

Answer»

`E_3^@=E_1^@+E_2^@`
`E_3^@=E_2^@-E_1^@`
`E_3^@=(n_1E_1^@+n_2E_2^@)/n_3`
`E_3^@=(n_1E_1^@+n_2E_2^@)/(n_3^2)`
