Application Rate of Reaction in Daily Life (3)

Not quite remember

I easily remember

Application of the concentration factor in combustion of petrol in car engines (1)

Petrol vapour and air are compressed in the car engine combustion chamber before being burned

Application of the concentration factor in combustion of petrol in car engines (2)

The compression increases the concentration of the petrol vapour allowing the petrol to burn very quickly until it explodes

Application of the concentration factor in combustion of petrol in car engines (3)

The energy released from the combustion of petrol will make the car move

Application of the temperature factor in cleaning (1)

Washing clothes using detergent powder and hot water combines two factors that increase the rate of reaction

Application of the temperature factor in cleaning (2)

The process of washing clothes will be even quicker using detergent powder and hot water

Application of the catalyst factor in catalytic converter (1)

Modern cars are fitted with catalytic converters to cut down atmospheric pollution

Application of the catalyst factor in catalytic converter (2)

Catalytic converters change pollutants from car engine into non-harmful products that are safe to be released into the atmosphere in the presence of platinum catalyst, Pt

Application of the temperature factor in cooking food (1)

Other than decreasing the size, food also cooks faster at high temperatures

Application of the temperature factor in cooking food (2)

Water boils at 100 °C while cooking oil would not boil even the temperature reaches 180 °C
