Topic 2 - Kinetic theory and factors affecting reaction rate

KINETIC THEORY

• kinetic theory= that molecules are in continual random motion, and that this can explain many of the factors that affect reaction rates.

• diffusion= the movement of a substance from a region of higher concentrationto a region of lower concentration.

• Brownian motion= the erratic random movement of microscopic particles, as a result of continuous bombardment from molecules surrounding it. 

• Heats of vaporisation can be used to compare the amounts of energy required to separate the same numbers of particles of different elements or compounds

• Imagine a gas with all its molecules in motion. They will collide with the walls of the container at intervals. This gives rise to pressure.
