What is diffusion rate dependent on?
The molar mass of the molecule. The heavier a gas molecule is, the slower it diffuses.
What is Dalton’s law?
Pressure per mole.
What is the kinetic theory of gases?
It is a set of assumptions based on the particle theory of nature.
What are the 6 kinetic theories of gases?
- Gases are composed of large numbers of atoms or molecules.
- The particles are in constant, random motion.
- The volume of the particles is insignificant compared to the volume between the particles.
- When gas molecules collide, no kinetic energy is lost.
- Electrical interaction between particles is insignificant.
- The kinetic energy of gas particles is proportional to absolute temperature.
