Problem: One of the components of polluted air is NO. It is formed in the high-temperature environment of internal combustion engines by the following reaction:N2 (g) + O2 (g) → 2NO (g),  ΔH = 180 kJWhy are high temperatures needed to convert N2 and O2 to NO?

FREE Expert Solution

Recall: An endothermic reaction absorbs heat from the surroundings. The change in enthalpy for endothermic reactions is positive. On the other hand, an exothermic reaction releases heat to the surrounding, and the change in enthalpy is negative.
