(B) The given reaction is $2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g)$ with $\Delta H = -45.2 \, kcal$.$1.$ The reaction is exothermic $(\Delta H $2.$ The number of moles of gaseous products is $2$,while the number of moles of gaseous reactants is $2 + 1 = 3$.$3.$ According to Le Chatelier's principle,for a reaction where the number of moles of gas decreases,an increase in pressure shifts the equilibrium towards the side with fewer moles,i.e.,the product side $(SO_3)$.Therefore,an increase in pressure favors the formation of $SO_3$.

Formation of $SO_3$ takes place according to the reaction:
$2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g); \,\, \Delta H = -45.2 \, kcal$
Which of the following factors favours the formation of $SO_3$?
