Factors Affecting Rate of Reaction

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.
Concentration 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.
