    In the following reversible reaction                 \[2S{{O}_{2}}+{{O}_{2}}\]⇌\[2S{{O}_{3}}+Q\]\[Cal\]                 Most suitable condition for the higher production of \[S{{O}_{3}}\] is [NCERT 1974; DPMT 1983, 89; IIT 1981; MP PET 1992; MP PMT 1990, 91, 94, 99; CPMT 1973, 77, 84, 89, 94, 99]

    A)                 High temperature and high pressure

    B)                 High temperature and low pressure

    C)                 Low temperature and high pressure

    D)                 Low temperature and low pressure

    Correct Answer: C

    Solution :

              Reaction is exothermic and volume is decreasing from left to right so for higher production of \[S{{O}_{3}}\] there should be low temperature and high pressure.
