nernst equation and electrolysis

Question 1

Nernst equation (E cell)

Answer 1

is used to calculate Ecell for non-standard concentrations.

E cell = Eo cell - RT/nF InQ

Question 2

relationship between Ecell and Eocell

Answer 2

if Ecell < Eocell then equilibrium shifts to the reactant

Question 3

electrolysis

Answer 3

the use of electrical energy to react non spontaneous redox reactions

Question 4

to determine current

Answer 4

current (I) = charge added (coulomb)/ time (sec)

Question 5

to determine the amount of charge added

Answer 5

charge = nF
where n = mole of electrons
F= faradays constant
