The reaction between sulphur (IV) oxide and oxygen is represented by the equilibrium reaction 2SO2(g) + O2(g) ↔ 2SO3(g), ∆H = -196 kJ. What factor would influence increased production of SO3(g)?
Addition of a suitable catalyst
Increase in the temperature of the reaction
Decrease in the temperature of the reaction
Decrease in the concentration of SO2(g)
