Copper reduces NO3 into NO and NO2 depending upon the concentration of HNO3 in solution Assuming fixed Cu and PNO PNO the HNO3 concentration at which the thermodynamic tendency for reduction of NO3 into NO and NO2 by copper is same is 10 M The value of 2x is Rounded off to the nearest integer Given E 0 34 V E 0 96 V Cu Cu NO NO RT ENO NO 0 79 V and at 298 K 0 79 V and at 298 K 2 303 F 3 0 0591
