JEE Main 2021 Chemistry question

Copper reduces into NO and depending upon the concentration of in solution. (Assuming fixed and ), the concentration at which the thermodynamic tendency for reduction of into NO and by copper is same is M. The value of 2x is. (Rounded-off to the nearest integer) [Given, = 0.34 V, = 0.96 V, = 0.79 V and at 298K, =0.059]
