Question:

Use the kinetic theory to justify the following observations:
(a) The rate of a reaction in the gas phase depends on the energy with which two molecules collide, which in turn depends on their speeds;
(b) In the Earth's atmosphere, light gases, such as H, and He, are rare but heavier gases, such as 0" CO2, and Nz, are abundant.
