Two identical spoons were electroplated with Ag or Cd through the use of the electrolytic cells illustrated above. 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. ΔG°= ΔH°−TΔS° B. ΔG°=−RT lnK C. E = E°−(RT/nF)lnQ D. I=q/t
