the reactant particles become more crowded the frequency of collisions between reactant particles increases the rate of reaction increases Note that the mean energy of the particles does not change.

If the concentration of solution is doubled, the number of particles in a given volume is doubled and so too are successful collisions in a given time. the horizontal line shows that no more product ...

Chemical reactions occur in a variety of situations with a wide range of different reaction types. Some chemical reactions occur extremely quickly, such as the explosion of a firework. Other chemical ...
