A staircase voltammogram was recorded for a \(1 \times 10^{-4} \mathrm{M}\) solution of a reversible iron complex in which the voltage was stepped \(5 \mathrm{mV}\) every \(10 \mathrm{~ms}\) sampling the current at \(5 \mathrm{~ms}\) following the voltage step. The sampled current gave a well-defined peak when it was plotted versus voltage. An Osteryoung square wave voltammogram for the same solution with a \(25 \mathrm{mV}\) squarewave with a net \(5 \mathrm{mV}\) step at \(100 \mathrm{~Hz}\) (current was sampled after \(5 \mathrm{~ms}\) for each voltage transition). All of the other conditions were the same for both experiments. Give two plausible reasons why the square wave signal was much larger than the staircase current peak.
