For the reduction of silver ions with copper metal, the standard cell potential was found to be +0.46 V at

25^\circ C

. The value of standard Gibb's energy,

\Delta G^\circ

will be (F = 96500 C mol

^{-1}

)

Step-by-Step Verified Solution

The cell reaction Cu + 2Ag + _ Cu 2+ + 2Ag We know, _ G� = � nFE� cell = � 2 _ 96500 _ 0.46 = � 88780 J = � 88.780 kJ = � 89 kJ
