The cell reaction Zn+Cu^(2+)rarrZn^(2+)+Cu , is best represented by-
Consider the following reaction, Zn(s)+Cu^(2+) (0.1 M) rarr Zn^(2+) (1 M)+Cu(s) above reaction, taking place in a cell, E_("cell")^(@) is 1.10 V. E_("cell") for the cell will be (2.303 (RT)/(F)=0.0591)
The standard emf for the cell cell reaction Zn + Cu^(2+) rarr Zn^(2+) + Cu is 1.10 volt at 25^@ C . The emf for the cell reaction when 0.1 M Cu^(2+) and 0.1 M ZN^(2+) solutions are used at 25^@ =C is .
The standard emf of the cell Zn+Cu^(2+)rarrCu+Zn^(2+) is 1.10V at 25^(@)c the emf of the cell when 0.1 M Cu^(2)+ and 0.1 M Zn^(2+) solution are used will be
Consider the cell Zn|Zn^(2+) || Cu^(2+)|Cu. If the concentration of Zn and Cu ions are doubled, the emf of the cell.
Consider the cell, Zn|Zn^(2+)(aq)(1.0M)||Cu^(2+)(aq)(1.0M)|Cu The standard reduction potentially are 0.350V for Cu^(2+)(aq)+2e^(-)rarrCu and -0.763V for Zn^(2+)(aq)+2e^(-)rarrZn (i) Write down the cell reaction (ii) Calculate the emf of the cell. (iii) Is the cell reaction spontaneous or not?
