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 : Pb | Pb 2 + || Cu 2+ |Cu

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

  • C u divided by C u to the power of 2 plus end exponent divided by divided by Z n to the power of 2 plus end exponent divided by Z n

E to the power of o space end exponent equals space E to the power of o Zn space minus sign space E to the power of o Cu space equals space minus sign 0 comma 76 space minus sign space left parenthesis plus 0 comma 34 right parenthesis space equals space minus sign 1 comma 10 space V

  • A g divided by A g to the power of plus divided by divided by F e to the power of 2 plus end exponent divided by F e

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

  • A g divided by A g to the power of plus divided by divided by Z n to the power of 2 plus end exponent divided by Z n

E to the power of o space end exponent equals space E to the power of o Zn space minus sign space E to the power of o Ag space equals minus sign 0 comma 76 space minus sign space left parenthesis plus 0 comma 80 right parenthesis space equals space minus sign 1 comma 56 space V

  • P b divided by P b to the power of 2 plus end exponent divided by divided by C u to the power of 2 plus end exponent divided by C u

E to the power of o space end exponent equals space E to the power of o Cu space minus sign space E to the power of o Pb space equals space plus 0 comma 34 space minus sign space left parenthesis minus sign 0 comma 13 right parenthesis space equals space plus 0 comma 47 space V

  • P b divided by P b to the power of 2 plus end exponent divided by divided by Z n to the power of 2 plus end exponent divided by Z n

E to the power of o space end exponent equals space E to the power of o Zn space minus sign space E to the power of o Pb space equals space minus sign 0 comma 76 space minus sign space left parenthesis minus sign 0 comma 13 right parenthesis space equals space minus sign 0 comma 63 space V

Maka, reaksi yang berlangsung spontan adalah : Pb | Pb2+ || Cu2+ |Cu
