JEE Main & Advanced Chemistry Equilibrium / साम्यावस्था Question Bank Topic Test - Chemical Equilibrium (6-5-21)

  • question_answer
    Consider the reaction equilibrium, \[2S{{O}_{2(g)}}\]+\[{{O}_{2(g)}}\]\[\rightleftharpoons \]\[2S{{O}_{3(g)}}\]; \[\Delta H{}^\circ \]= –198kJ. 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) Increasing temperature as well as pressure

    C) Lowering the temperature and increasing the pressure          

    D) Any value of temperature and pressure

    Correct Answer: C

    Solution :

    [c] It is an exothermic reaction hence low temperature and increasing pressure will favour forward reaction.
