Questions and Answers

What is the relationship between electrical energy and quantity of electricity in electrochemistry?

Electrical energy = Emf (volts) $\times$ Quantity of electricity (coulombs) (correct)

Electrical energy = Emf (volts) $-$ Quantity of electricity (coulombs)

Electrical energy = Emf (volts) $+$ Quantity of electricity (coulombs)

Electrical energy = Emf (volts) $\div$ Quantity of electricity (coulombs)

What is the standard representation for the standard emf of a cell?

E$^\circ$cell = E$^\circ$cathode $+$ E$^\circ$anode

E$^\circ$cell = E$^\circ$cathode $\div$ E$^\circ$anode

E$^\circ$cell = E$^\circ$cathode $\times$ E$^\circ$anode

E$^\circ$cell = E$^\circ$cathode $-$ E$^\circ$anode (correct)

What is the potential of the Standard Hydrogen Electrode (SHE) assigned as?

E$^\circ$ = -1 V

E$^\circ$ = 0 V (correct)

E$^\circ$ = 1 V

E$^\circ$ = 0.5 V
