A student made measurements on some electrochemical cells and calculated three quantities:
The standard reaction free energy ΔG°.
The equilibrium constant K at 25 °C.
The cell potential under standard conditions E°.
His results are listed below.
calculated quantities
cell n (Identify any that are wrong.)
ΔG° K E°
A 2 -156. kJ / mol 4.68 x 10^(-28) 0.81 v
B 2 -147. kJ / mol 5.67 x 10^(25) -0.76 v
C 2 -69. kJ /mol 8.16 x10^(-13) -0.36 v

Unfortunately, the student may have made some mistakes. Examine his results carefully and identify the incorrect quantity in each row, if any.
Note: If there is a mistake in a row, only one of the three quantities listed is wrong.
Also, you may assume the number of significant digits in each quantity is correct. Also note: for each cell, the number of electrons transferred per redox reaction is 2.
