The cyclic voltammogram of the antibiotic chloramphenicol (abbreviated RNO_(2) ) is shown here. The scan was started at 0.0V, and potential was swept toward negative voltage. The first cathodic wave, A, is from the reaction RNO_(2)+4e^(-)+4H^(+)?RNHOH+H_(2)O. Explain what happens at peaks B and C by using the reaction RNO+2e^(-)+2H^(+)?RNHOH. Why was peak C not seen in the initial scan? Cyclic voltammogram of 3.70 xx10^(-4)M chloramphenicol in 0.10M acetate buffer, pH4.62. The voltage of the carbon paste working electrode was scanned at a rate of 350mV//s.
