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)

in an exothermic rxn increase in temp favours backward rxn automatically a decrease in temp will favour forward rxn which will result to increase in the yield of SO3
this question is just causing me so much brain commotion
the answer is both A and C
SO2 does not just react with O2 with some enabling conditions like a catalyst (in this case vanadium (V) oxide) and a decrease in heat and high pressure
buh I go for mainly because catalyst does all the trick or f lowering the activation energy so for me temperature doesn't matter all dat much
all the best
Smarty
it z c because of the d reaction z exothemic ie loss of energy in d system nd wen there z decrease it will favours d foward reaction
