New cards

The standard cell potential WHAT is determined by WHAT the E°r values of the WHAT

The standard cell potential (E°net) is determined by SUBTRACTING the E°r values of the TWO HALF REACTIONS

2
New cards

If you multiply an equation by the balance electrons, you WHAT multiply the E° value (voltage is WHAT of number of electron transferred)

If you multiply an equation by the balance electrons, you DO NOT multiply the E° value (voltage is INDEPENDENT of number of electron transferred)

New cards

A POSITIVE E°net is a WHAT reaction

SPONTANEOUS

4
New cards

A NEGATIVE E°net is a WHAT reaction

NON-SPONTANEOUS

5
New cards

The formula for this is

E°net = E°r cathode - E°r anode
