In car engines or when lightning occurs during thunderstorms, nitrogen and oxygen react to form oxides of nitrogen at high temperatures. What is the main reason that these reactions need such high temperatures?
- Athe lack of reactivity of nitrogen, due to the half-filled $2p$ subshell in the nitrogen atom
- Bthe lack of reactivity of nitrogen, due to the strength of the bond in $\text{N}_2$
- Cthe lack of reactivity of oxygen, due to electron-electron repulsion in one of its $2p$ orbitals
- Dthe lack of reactivity of oxygen, due to the strength of the bond in $\text{O}_2$
