The emf of the following three galvanic cells : 1. Zn//Zn^(2+) ( 1M) || Cu^(2+) (1 M) //Cu 2. Zn//ZN^(2+ ) (1 M)|| Cu^(2+) //cu 3. Zn//Zn^(2+) (1 M) || Cu^(2+) (0.1 M) Cu are repersented by E_1, E_2, E_3 which of the following statement is true ?

In the cell, Zn|Zn^(2+)"||"Cu^(2+)|Cu ________.

The standard cell potential for the cell Zn|Zn^(2+) (1 M)|| Cu^(2+) (1 M)| Cu Given E_(Cu^(2+)//Cu)^(@) = 0.34 V and E_(Zn^(2+)//Zn)^(@) = - 0.76 V is

E_(1) , E_(2) and E_(3) are the emfs of the following three galvanic cells respectively I. Zn((s)) | Zn^(2+) (0.1M) | | CU^(2+) (1M) | Cu((s)) II. Zn((s)) ZN^(2+) (1M) || Cu^(2+)(1M) | Cu(s) III. Zn(s) | Zn^(2+) (1M) || CU^(2+)(0.1M)CU(s)
