In the industrial manufacture of , the endothermic reaction is carried out. Which condition is most — Chemical Equilibrium Chemistry Question
Question
In the industrial manufacture of $NO$, the endothermic reaction $N_2(g) + O_2(g) \rightleftharpoons 2NO(g) - Q\text{ kcal}$ is carried out. Which condition is most favorable for a higher production of $NO$?
Answer: C
💡 Solution & Explanation
The given reaction is endothermic (heat is absorbed, indicated by $-Q\text{ kcal}$). By Le-Chatelier's principle, increasing the temperature favors the endothermic direction, shifting the equilibrium forward to produce more $NO$. Since $\Delta n_g = 2 - 2 = 0$, pressure changes have no effect on the equilibrium position.
