  • Question 1/10
    1 / -0

    In a closed system: A(s) ⇌ 2B(g) ​​​​​​​⇌ 3C(g) if the partial pressure of C is doubled, then partial pressure of B will be

    Solutions

     

  • Question 2/10
    1 / -0

    The initial pressure of COCl2 is 1000 torr. The total pressure of the system becomes 1500 torr, when the equilibrium is attained at constant temperature.

    The value of Kp of a reaction is

    Solutions

     

  • Question 3/10
    1 / -0

    Which set can explain chemical equilibrium?

    Solutions

    At equilibrium

     

  • Question 4/10
    1 / -0

    The first and second dissociation constants of an acid H2A are 1.0 × 10-5 and 5.0 × 10-10 respectively. The overall dissociation constant of the acid will be

    Solutions

     

  • Question 5/10
    1 / -0

    The exothermic formation of CIF3 is represented by the equation :

    Which of the following will increase the quantity of CIF3 in an equilibrium mixture of Cl2, F2 and CIF3 ?

    Solutions

    The reaction given is an exothermic reaction thus accordingly to i.e. chatalier’s principle dowering of temperature, addition of F2 and Cl2 yarour the forward direction and hence the production of CIF3 .

     

  • Question 6/10
    1 / -0

    Which of the following equilibrium does not effected with the change in volume of the system?

    Solutions

    In the nitric oxide formation reaction, both the reactants and the product possessequal moles. Hence, change in volume does not affect the equilibrium of reaction.

     

  • Question 7/10
    1 / -0

    A saturated solution of iodine in water is 1.25 × 10–3 (M). In any saturated solution of l2 concentration of l2 is 1.25 × 10–3 (M). In 1 L of 0.1 (M) solution I– , it is seen 51.25 × 10–3 mole of l2 can be maximum dissolved. In the aqueous solution of l– (aq), l2 (ag) undergoes complex formation, 

    What is the value of KC ?

    Solutions

     

  • Question 8/10
    1 / -0

    The percentage of ammonia obtainable, if equilibrium were to be established during the Haber process, is plotted against the operating pressure for two temperatures, 400ºC and 500ºC. Which of the following graph correctly represent the two process?

    Solutions

    By Le-Chatelier principle, higher pressure and lower temperature favour the forward reaction, i.e., higher % of NH3 .

     

  • Question 9/10
    1 / -0

    Dissociation constants of CH3COOH and NH4OH are 1.8 × 10-5 each at 25°C. The equilibrium constant for the reaction of CH3COOH and NH4OH will be:

    Solutions

     

  • Question 10/10
    1 / -0

    In an aqueous solution of volume 500 ml, when the reaction of reached equilibrium the [Cu+2] was x M. When 500 ml of water is further added, at the equilibrium [Cu+2]  will be

    Solutions

    ∴ Reaction go backward and concentration of [Cu+2] < x / 2
