Two identical spoons are electroplated with Ag or Cd through the use of the electrolytic cells. A current of 5.00A was supplied to each cell for 600 seconds, and the masses of the spoons before and after the electroplating were recorded. Which of the following mathematical equations can best be used to account for the much larger increase in mass of the spoon electroplated with Ag compared with the spoon electroplated with Cd? a. ÎG°= ÎH°âTÎS°
b. ÎG°=âRT lnK
c. E = E塉(RT/nF)lnQ
d. I=q/t
