  • Assertion : In the dissociation of PCl_(5) at constant pressure and temperature addition of helium at equilibrium increases the dissociation of PCl_(5) . Reason : Helium reacts with Cl_(2) and hence shifts the equilibrium in forward direction.

    A
    If both assertion and reason are true and reason is the correct explanation of assertion.
    B
    If both assertion and reason are true but reason is not the correct explanation of assertion.
    C
    If assertion is true but reason is false.
    D
    If both assertion and reason are false.

    A helium atom, a hydrogen atom and a neutron have mases of 4.003 u, 1.008 u and 1.009 u (unified atomic mass units), respectively. Assuming that hydogen atoms and neutrons can be fuse to from helium, what is the binding energy of a helium nucleus?

    Assertion : One mole of helium atoms should occupy 22.4 litres volume at STP Reason : Taking 31 pm as radius of helium atoms, if we pack together a mole of helium atoms, the mole of atoms should have a volume of 22.4 litre

    Statement I : Balloons made by nylon films are better for containing helium than the conventional rubber balloons. Statement II : R.M.S. velocity of helium is very high. So helium atom can effuse out through rubber balloons.

    A tank used for filling helium balloons has a volume of 0 .3 m^3 and contains (2.0) mol of helium gas at 20 .0^@ C . Assuming that the helium behaves like an ideal gas. (a) What is the total translational kinetic energy of the molecules of the gas ? (b) What is the average kinetic energy per molecule ?

    A sample of helium and neon gases has a temperature of 300 K and pressure of 1.0 atm . The molar mass of helium is 4.0 g//mol and that of neon is 20.2 g//mol . (a) Find the rms speed of the helium atoms and of the neon atoms. (b) What is the average kinetic energy per atom of each gas ?

    The root mean square velocity of the molecules in a sample of helium is 5//7th that of the molecules in a sample of hydrogen. If the temperature of hydrogen sample is 0^(@)C , then the temperature of the helium sample is about
