Question 1

Coulombs

Answer 1

1.6 x 10^-19 C

Question 2

Faraday Constant

Answer 2

96,485 C/Mol e^-

Question 3

Standard EMF

Answer 3

EMF = E^o_red + E^o_ox

do not multiply with moles

Question 4

EMF and Gibbs Free Energy

Answer 4

ΔG = -nFE_cell

ΔG^o = -nFE^o_cell

F expressed as J/V = C

ΔG expressed in J

Question 5

Effect of [] on EMF

Answer 5

E_cell = E^o_cell - (RT/nF)(lnQ)

Measured with a voltmeter or potentiometer

Question 6

EMF and K_eq

Answer 6

ΔG^o = -RTlnK_eq

nFE^o_cell = RTlnK_eq
