$Cu^{+2} + 2e^-\to Cu$ ; $E^o = X_2$ then the value of $E^o$ for $Cu^{+2} + e^-\to Cu^+$ will be

In the above first order reaction the initial concentration of $\mathrm{N}_{2} \mathrm{O}_{5}$ is $2.40 \times 10^{-2}\, \mathrm{~mol} \,\mathrm{~L}^{-1}$ at $318 \,K.$ The concentration of $\mathrm{N}_{2} \mathrm{O}_{5}$ after $1\, hour$ was $1.60 \times 10^{-2}\, \mathrm{~mol} \,\mathrm{~L}^{-1}$, The rate constant of the reaction at $318\, \mathrm{~K}$ is $.....\,\times 10^{-3} \mathrm{~min}^{-1}$. (Nearest integer)

[Given: $\log 3=0.477, \log 5=0.699$ ]

What is the value of $x$ in the above reaction ?
