    Few questions from the practice paper are given below:

    Q.     According to kinetic theory of gases collisions are always elastic

    (a)   heavier molecules transfer more momentum to the wall of the container

    (b)  only a small number of molecules have very high velocity

    (c)   between collisions, the molecules move in straight lines with constant velocities

    (d)  between collisions, the molecules move in straight lines with constant velocities

    Sol.

    Correct Option: (a)

    According to a postulate of kinetic theory of gases, collision between the    molecules as well as with the wall of container is perfectly elastic in nature.

    Hence, option (a) is correct

    All other statements are incorrect.

    Q.    Benzene and naphthalene form an ideal solution at room temperature. For this process, the true statement(s) is (are)

    (a)  ΔG is positive                      

    (b)  ΔS system is positive

    (c)  ΔS surroundings = 0

    (d) ΔH =

    Correct Option(s): (b), (c), (d)

    Sol.

    When an ideal solution is formed process is spontaneous

    According to Raoult's law, for an ideal solution

    ΔH = 0, ΔVmin = 0

    From the relation

    ΔG = ΔH ΔS

    Since, ΔH =

    ΔG = – ve

    and ΔS surroundings = 0

    Therefore, ΔS sys. = + ve

    Q. In the titration of HClversus NaOH, the pH of the solution at equivalence point (when temperature is 25C) is

    Correct Answer: 7

    Sol.

    At the equivalence point, the solution will contain NaCl. Its pH would be 7.
