Factors Affecting Rate of Reaction

 
4.2  Factors Affecting Rate of Reaction
 
1. Factors affecting rate of reaction
 
Factors Explanation
Temperature of reactants
  • When the temperature of reactants increases, the rate of reaction increases.
  • When the temperature of reactants decreases, the rate of reaction decreases.
Concentratio of reactants
  • When the concentration of reactants increases, the rate of reaction increases.
  • When the concentration of reactants decreases, the rate of reaction decreases.
Size of solid reactants
  • When the size of solid reactants decreases, the rate of reaction increases.
Presence of catalyst
  • When catalyst is used in a reaction, the rate of reaction increases.
Pressure
  • When pressure increases, the rate of reaction involving gaseous reactants increases.
  • When pressure decreases, the rate of reaction involvimh gaseous reactants decreases.
