Calculate the standard free energy change for the reaction , 2 Ag + 2 H^(+) to H_(2) + 2 Ag^(+) , E^(@) for Ag^(+) + e^(-) to Ag is 0.80 V

Answer»

`+ 154.4` KJ
`+ 308.8` kJ
`-154.4 ` kJ
`-308.8` kJ

SOLUTION :For the given reaction `E_(cell)^(@) = -0.80` V
`DELTA G^(@) = -n F E_(cell)^(@)`
= `-2 xx 96500 xx (-0.80) J = 154.4 kJ` .
