    Consider the reaction equilibrium, \[2S{{O}_{2}},\,\,(g)\,\,{{O}_{2}},\,\,(\,g)\rightleftharpoons 2\,S{{O}_{3}}(g),\,\,\Delta H{}^\circ =-198\,\,KJ\]on the basis of Le-chatelier's principle, the condition favourable for the forward reaction is

    A) lowering of temperature as well as pressure       

    B) lowering the temperature and increasing the pressure

    C) increasing the temperature and pressure           

    D) any value of temperature and pressure

    Correct Answer: B

    Solution :

    An exothermic reaction is a chemical reaction that releases energy in the form of light or heat. The given reaction is an exothermic reaction, hence low temperature and increasing pressure will favour forward reaction.
