Even at relatively low pressures, there is a 99.5% conversion of sulphur dioxide into sulphur trioxide. The very small improvement that you could achieve by increasing the pressure isn't worth the expense of producing those high pressures.

you can find all Cambridge syllabus from 2002 to 2021 past papers , notes , flashcards etc on multiple websites
such as
Xtremepape.rs
papers.gceguide
papacambridge.com etc

and also I don't think so there was any 0625/22/f/m/08 paper held by Cambridge.
