ΔG 계산. Cu|Cu2^+(0.0200 M)||Ag^+(0.0200 M)|Ag

 

 

다음 셀의 열역학 퍼텐셜과 셀 반응과 관련된 자유 에너지 변화를 계산하시오.

Cu | Cu2^+ (0.0200 M) || Ag^+ (0.0200 M) | Ag

> Ag^+ + e^- → Ag(s) ... E° = +0.799 V

> Cu^2+ + 2e^- → Cu(s) ... E° = +0.337 V

 

---------------------------------------------------

 

Ecell = +0.412 V

( 참고 https://ywpop.tistory.com/18119 )

 

 

 

ΔG = –nFEcell

( 참고 https://ywpop.tistory.com/10066 )

 

= –(2) (96485 C/mol) (0.412 V)

= –(2) (96485 J/V•mol) (0.412 V)

= –79504 J/mol

= –79.5 kJ/mol

 

 

 

답: –79.5 kJ/mol
