JEE Main & Advanced Chemistry Equilibrium / साम्यावस्था Question Bank Le-Chatelier principle and it's application

  • question_answer
    Sodium sulphate dissolves in water with evolution of heat. Consider a saturated solution of sodium sulphate. If the temperature is raised, then according to Le-Chatelier principle                                   [MP PET 2000]

    A)                 More solid will dissolve

    B)                 Some solid will precipitate out from the solution

    C)                 The solution will become supersaturated

    D)                 Solution concentration will remain unchanged

    Correct Answer: B

    Solution :

              When temperature increases precipitation of sodium sulphate takes place. Because reaction is exothermic so reverse reaction will take place.
