Exam 5 Formulas

Question 1

What is the Nernst equation?

Answer 1

E_cell = E^º_cell - RT/nF x ln(Q)

Question 2

What is the formula that relates free energy to the equilibrium constant?

Answer 2

G = -RTlnK

Question 3

How do you calculate moles of reaction from current?

Answer 3

(I x t)/(nF) = moles of reaction

Question 4

How do you calculate the standard cell potential using standard reduction potentials?

Answer 4

E_cell = E_cathode - E_anode

all are standardized

Question 5

What is the formula for current?

Answer 5

current = charge/time

Question 6

What is the formula that relates cell potential to free energy?

Answer 6

G = -nFE
