Transcribed Image Text:Electroplating is rarely 100% efficient-some of the current usually is consumed by reactions other
than the desired reduction reaction. The current efficiency is the fraction of charge that does go into
the desired reduction reaction. When a current of 6.00 A flows for 15.0 minutes through a cell
composed of two Pt electrodes in a solution of Cu(NO3)2(aq) in dilute HNO3(aq), 0.40 g of copper is
deposited on the cathode.
(a) Calculate the current efficiency for this process.

(b) If the remainder of the current reduces equal amounts of hydronium (to hydrogen gas and
water) and nitrate ions (to NO(g)), calculate the volumes of H2(g) and NO(g) generated (in L) per
hour at 1 bar and 30°C.
