Exam 5 Formulas Flashcards
1
Q
What is the Nernst equation?
A
Ecell = Eºcell - RT/nF x ln(Q)
2
Q
What is the formula that relates free energy to the equilibrium constant?
A
G = -RTlnK
3
Q
How do you calculate moles of reaction from current?
A
(I x t)/(nF) = moles of reaction
4
Q
How do you calculate the standard cell potential using standard reduction potentials?
A
Ecell = Ecathode - Eanode
all are standardized
5
