For the equilibrium reaction 2SO₂(g) + O₂(g) ⇌ 2SO₃(g), $\Delta$Hº_rxn = -198 kJ/mol. Which one of these factors would cause the equilibrium constant to increase

Question

Quizplus · Accepted Answer

Given that the reaction is exothermic ($\Delta H_{rxn}^{\circ} = -198 kJ/mol$), decreasing the temperature will favor the formation of products, thereby increasing the equilibrium constant.

For the Equilibrium Reaction 2SO2(g) + O2(g) ⇌ 2SO3(g) Δ\DeltaΔ Hºrxn = -198 KJ/mol

For the Equilibrium Reaction 2SO₂(g) + O₂(g) ⇌ 2SO₃(g) $\Delta$ Hº_rxn = -198 KJ/mol
