Pembahasan

Reaksi yang berlangsung spontan, merupakan reaksi yang berlangsung tanpa pemicu dan menghasilkan arus listrik (harga E o sel positif). Pb -> Pb +2 + 2e E o = +0,13 volt Cu +2 + 2e -> Cu E o = +0,34 volt + Pb + Cu +2 -> Pb +2 + Cu E o = +0,47 volt

Reaksi yang berlangsung spontan, merupakan reaksi yang berlangsung tanpa pemicu dan menghasilkan arus listrik (harga Eosel positif).

Pb -> Pb+2 + 2e                         Eo = +0,13 volt

Cu+2 + 2e -> Cu                         Eo = +0,34 volt +

Pb + Cu+2 -> Pb+2 + Cu           Eo = +0,47 volt
