Factors that Affect the Rate of Reaction (3)

Chemistry

Not quite remember

I easily remember

Factors affecting rate of reaction - temperature (2)

The rate of reaction increases with increasing temperature

Factors affecting rate of reaction - temperature (3)

For reactions that occur at room temperature, each increase of 10 °C will increase the reaction rate by 2 times

The effect of temperature on the rate of reaction

The higher the temperature of reactants, the shorter the time taken for the ‘X’ mark to disappear from view

Factors affecting rate of reaction - presence of catalyst (1)

Catalysts are chemical substances that alter the rate of chemical reactions without undergoing any chemical changes at the end of the reaction

Factors affecting rate of reaction - presence of catalyst (2)

Although the chemical properties of the catalyst does not change, but its physical properties can change

Factors affecting rate of reaction - presence of catalyst (3)

Catalysts do not change the quantity of products

The effect of catalyst on the rate of reaction

Presence of catalyst increases the rate of reaction

The effect of increasing concentration of reactants on the rate of reaction

Rate of reaction increases

The effect of increasing of temperature on the rate of reaction

Rate of reaction increases

The effect of presence of catalyst on the rate of reaction

Rate of reaction increases
