Oxidation reaction takes place by addition reaction, So3 in unstable state it require pressure to with hold, hence it require higher pressure.

Pankaj said: (Jan 27, 2014)
Oxidation of SO2 +O2= SO3 is exothermic reaction reaction. To increase SO3 concentration temperature to be kept low says by Le-chatelier's principle. On increasing pressure the reaction shift where the number of mole decrease.

Chandu said: (Sep 15, 2015)
According to Le-chatelier's principle here left to right no of moles decrease. On increasing pressure the reaction shift where the number of mole decrease.
