23.5 Predictions from electrode potentials Flashcards
1
Q
what are the limitations of predictions using E⊖ values?
A
reaction rate
concentration
if not standard conditions
2
Q
how is the reaction rate a limitation?
A
electrode potentials don’t give any indication to the rate of reaction as different reactions would have different activation energies
3
Q
how is concentration a limitation?
A
if the concentration of the solution is not 1 mol dm-3 then it is no longer a standard solution so the standard electrode potential is different
4
Q
what happens if the concentration is not 1 mol dm-3?
A
the EQ will either shift left or right causing a disruption to the flow of electrons
