ldentify the minimum possible temperature at which all molecular motion ceases

Absolute zero is the minimum temperature that can be reached by a system. Explain why temperature below absolute zero is not possible

Maxwell and Boltzmann have shown that actual distribution of molecular speeds depends on temperature and molecular mass. At the same temperature which will move faster, N_2 or Cl_2 ?

A certain volume of Ar gas require 45 sec to effuse through a hole at a certain pressure and temperature. The same volume of another gas of unknown molecular weight require 60 sec to pass through the same hole under the same condition of temperature and pressure. The molecular weight of gas is

A reaction, 'A+B rarr C+D+q' is found to have a positive entropy change. The reaction will be i) possible at high temperature ii) possible oniy at low temperature iii) not possible at any temperature iv) possible at any .temperature.

Maxwell and Boltzmann have shown that actual distribution of molecular speeds depends, on temperature and molecular mass. What do you mean by most probable velocity?
