  • Question 1
    1 / -0

    In any chemical reaction, equilibrium is supposed to be establish when

    Solution

    When rate of forward reaction is equal to the rate of backward reaction then equilibrium is supposed to be established.

     

  • Question 2
    1 / -0

    Which of the following conditions represents an equilibrium

    Solution

    Equilibrium can be achieved only in closed vessel.

     

  • Question 3
    1 / -0

    In chemical reaction A B, the system will be known in equilibrium when

    Solution

    When rate of forward reaction is equal to rate of backward reaction the reaction is said to be in equilibrium.

     

  • Question 4
    1 / -0

    In the chemical reaction N + 3H2 ⇌ 2NHat equilibrium point, state whether

    Solution

    At equilibrium rate of forward reaction is equal to the rate of backward reaction.

     

  • Question 5
    1 / -0

    For the reaction PCl3(g) + Cl2(g) ⇌ PCl5(g) the position of equilibrium can be shifted to the right by

    Solution

    According to Le-chatelier principle when concentration of reactant increases, the equilibrium shift in favour of forward reaction.

     

  • Question 6
    1 / -0

    If a system is at equilibrium  the rate of forward to the reverse reaction is

    Solution

    At equilibrium, the rate of forward & backward reaction become equal.

     

  • Question 7
    1 / -0

    According to law of mass action rate of a chemical reaction is proportional to

    Solution

    According to law of mass-action, “at a given temperature, the rate of a reaction at a particular instant is proportional to the product of the active masses of the reactants at that instant raised to powers which are numerically equal to the numbers of their respective molecules in the stoichiometric equation describing the reaction”.

     

  • Question 8
    1 / -0

    Which is false

    Solution

    As we increase the concentration of substance, then speed of the reaction increases.

     

  • Question 9
    1 / -0

    Chemical equations convey quantitative information on the

    Solution

    Chemical reaction quantitatively depend on the reactant and product molecule.
