Zn((s))+Fe(aq)^(2+) Leftrightarrow Zn(aq...

`Zn_((s))+Fe_(aq)^(2+) Leftrightarrow Zn_(aq)^(2+) +Fe_((s)`. The vale of `K_(c)`for this reaction is `10^(23). Calculate the standard free energy change.

Text Solution

Verified by Experts

Change in standard free energy,
`Delta G ^(@) =- 2l303 RT log _(10) K _(c)`
`Delta G ^(@) =- 2.303 xx 1.987 xx 298 xx log 10 ^(23)`
`=- 13.570 cal mol ^(-1)`
Standard free energy change for the reaction is `- 13.57 kcal mol^(-1)`
