Question

At constant pressure, the reaction 2NO₂(g) $\rightarrow$ N₂O₄(g) Is exothermic. The reaction (as written) is

Quizplus · Accepted Answer

The reaction is exothermic, meaning it releases heat. At low temperatures, the entropy decrease (due to fewer gas molecules) is outweighed by the enthalpy decrease, making the reaction spontaneous. At high temperatures, the entropy term becomes more significant, potentially making the reaction non-spontaneous.

At Constant Pressure, the Reaction 2NO2(g) →\rightarrow→ N2O4(g) Is Exothermic
