A 20-mm cube of copper metal is placed in 250 ml of 12 M nitric acid at 25°C and the reaction below occurs:
Cu(s) + 4H+ (ag) + 2NO3-(aq) -> Cu2+ (aq) + 2NO2(g) + 2H20(l)
At a particular instant in time, nitrogen dioxide is being produced at the rate of 3.6 x 10^-4 M/min. At this same instant, what is the rate at which nitrate ions are being consumed
in M/min?
