The reversible reaction occurs in a closed industrial vessel. Which combination of external pressure — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

The reaction is highly exothermic ($+362\text{ kcal}$ released). Low temperatures favor exothermic reactions. $\Delta n_g = 1 - 3 = -2$. High pressure favors the direction producing fewer moles of gas. Thus, highest pressure ($1000\text{ atm}$) and lowest temperature ($50^\circ\text{C}$) maximize yield.
