The Effects of Current and Potential on Rate and Equilibrium (Grade 12 NSC Matric Physical Sciences): Flashcards

Flow of electrons

Faster rate of electrochemical reaction

$\text{Zn(s)} \rightarrow \text{Zn}^{2+}\text{(aq)} + 2\text{e}^-$

$\text{Cu}^{2+}\text{(aq)} + 2\text{e}^- \rightarrow \text{Cu(s)}$

Faster electron flow

Increases rate of decomposition

Zero

Constant

0 (equilibrium reached)

How far reaction is from equilibrium
