Chemical reaction rates depends on factors that influence the frequency of collisions between reactant molecules.
The rate of reaction = the decrease in concentration of reactants OR the increase in concentration of products within a given time interval. (change in concentration / time)(change in concentration / time)
Reaction Rates (Reactions occur due to COLLISIONS)(Reactions occur due to COLLISIONS)
Reaction Rates (Reactions occur due to COLLISIONS)(Reactions occur due to COLLISIONS)Reaction rates depend on factors such as:1)Temperature (↑↑ temp. = ↑↑ rxn rate)2)Concentration (↑↑ conc. = ↑↑ rxn rate)3)Particle size (smallersmaller size. = ↑↑ rxn rate)4)Catalyst (with catalystwith catalyst. = ↑↑ rxn rate)5)Pressure (↑↑ pressure. = ↑↑ rxn rate) (DEPENDSDEPENDS)
Catalysts play a role in increasing the reaction rate by changing (lowering) the activation energy in a chemical reaction.
According to collision theory, atoms, ions, and molecules can react to form products when they collide with one another, provided that provided that the colliding particles have enough kinetic the colliding particles have enough kinetic energyenergy.

Particle Size (and SURFACE AREA)
The minute size of the reactant particles (grain dust), and the mixture of the grain dust with oxygen in the air caused the reaction to be explosive, destroying the grain elevator.

An inhibitor is a substance that interferes with the action of a catalyst. Antioxidants and antimicrobials used in drying fruits and preserving fruit juices slow the action of microbes and limit contact with air.
