Electrochemistry Part 1

Copper reduces NO3−into NO and NO2 depending upon the concentration of HNO3 in solution. (Assuming fixed [Cu2+] and pNO=pNO2 ), the HNO3 concentration at which the thermodynamic tendency for reduction of NO3−into NO and NO2 by copper is same is 10xM. The value of 2x is ............ .(Rounded off to the nearest integer)
