Factors Affecting Reaction Rates
Concentration
Increasing the concentration increases the probability of a collision between reactant particles. With more particles in the same volume, collisions are more frequent, speeding up the reaction rate. Conversely, a lower concentration leads to fewer collisions and a slower reaction rate.
Surface Area
If a solid reactant or catalyst is broken down into smaller pieces, the rate of reaction increases. This is because smaller pieces of the same mass have a greater surface area, providing more opportunities for reactant particles to collide with the surface and react.
Types of Rate Laws
Differential Rate Law: Describes how the rate of a reaction depends on the concentration of reactants (often simply called... Continue reading "Factors Affecting Reaction Rates and Rate Laws" »
