Consider the reaction equilibrium
2SO_2 (g) + O_2 (g)[IMAGE] 2SO_3 (g); ΔHº = - 198 kJ.
On the basis of Le Chatelier's principle, the condition favourable for
the forward reaction is
Show answer and solution
The conversion of SO2 to SO3 is an exothermic reaction, hence
there is no need to increase the temperature. There is also a decrease
in volume or moles in product side. Thus the reaction is favoured by low
temperature and high pressure. (Le-Chatelier's principle).
