Calculate DetlaG^(@) for the following r...

Calculate `DetlaG^(@)` for the following reaction, `Zn_((s)) + Cu_((aq))^(2+) to Zn_((aq))^(2+) + Cu_((s)) . DeltaG_(f)^(@)` of `Zn_((aq))^(2+)` and `Cu_((aq))^(+2) is `-147.2 kJ mol^(-1)`and `65kJmol^(-1)` .

Text Solution

Verified by Experts

Standard free energy change,
`Delta G ^(@) = sum Delta G _(f) ^(@) ` of products `- sum Delta G _(f) ^(@) ` of reactants.
`Delta G ^(@) = (- 147 . 2 + 0) - ( 0+ 65)=212.2 kJ mol ^(-1).`
