                                                              Answer the following questions:

  1.   What is the significance of distribution of molecular velocities of a gas at different temperature?
  2. Briefly describe the term “average speed” according to Maxwell-Boltzmann distribution. 
  3.   Explain how increasing the temperature increasing the rate of reaction using the Maxwell-Boltzmann distribution curve.
  4. List three types of inter-molecular forces and state the weakest with a convincing reason.
  5. Determine the molecular mass of Neon whose density is 0.263g/dm3 with 0.337atm at 308K temperature.
  6. State the law of equi-partition of energy.
  7. Calculate the values of most probable velocity, average velocity and root-mean-square velocity for Nitrogen molecules at 27oC [Universal gas constant=8.314(Kgm2/s2) K-1Mol-1].
