The correct answer is: $0.5 \mathrm{~atm}$
$$
\begin{array}{rlrl}
\because & { }^n \mathrm{CO} & ={ }^n \mathrm{~N}_2 \\
& \therefore & p_{\mathrm{CO}} & =p_{\mathrm{N}_2} \\
\text { Given, } & p_{\mathrm{CO}}+p_{\mathrm{N}_2} & =1 \mathrm{~atm} \\
& \text { or } & 2 p_{\mathrm{N}_2} & =1 \mathrm{~atm} \\
\text { or } & p_{\mathrm{N}_2} & =0.5 \mathrm{~atm}
\end{array}
