The reaction that is endothermic among the options given is:
\[ \text{N}_2 + \text{O}_2 \rightarrow 2\text{NO} \]
This reaction requires energy input to occur, which is typical for reactions that produce compounds from elemental gases. The other reactions listed are generally exothermic, as they involve the formation of more stable products (like CO2 and SO2) from their elemental reactants, releasing energy in the process.
