Pembahasan

Reaksi yang dapat berlangsung spontan adalah reaksi yang memiliki nilai E°selpositif. Pada notasi sel berlaku : oksidasi || reduksi Maka, reaksi yang berlangsung spontan adalah Ni| Ni 2 + || Pb 2+ | Pb

Reaksi yang dapat berlangsung spontan adalah reaksi yang memiliki nilai E°sel positif.

E degree equals space E degree R e d u k s i minus space E degree space o k s i d a s i 

Pada notasi sel berlaku : oksidasi || reduksi

  • Ag forward slash Ag to the power of plus sign forward slash forward slash Fe to the power of 2 plus sign forward slash Fe

E to the power of o equals space E to the power of o Fe space minus sign space space E to the power of o Ag space equals space left parenthesis minus sign 0 comma 44 right parenthesis space minus sign space left parenthesis plus 0 comma 80 right parenthesis space equals space plus 1 comma 24 space V
