About Factors Affecting Rate of Reaction
Reaction rate depends on the nature and concentration of reactants, pressure for gases, temperature, surface area and catalysts. Collision theory explains these effects through collision frequency, orientation and activation energy, while questions often distinguish a catalyst's effect on reaction rate from its lack of effect on equilibrium composition.
