Application Rate of Reaction in Daily Life

 
7.3 Application of Factors that Affect the Rate of Reaction in Daily Life
 
This image is an infographic titled ‘FACTORS THAT AFFECT THE RATE OF REACTION IN DAILY LIFE.’ It features four columns, each representing a different factor. Each column has a number at the top and a label below: 1. The Size Factor 2. Concentration Factor 3. Temperature Factor 4. Catalyst Factor The background is white, and the text is in blue. The logo ‘Pandai’ is present on the right side.
  
The Size Factor
Action of Medicines
  • Antacid tablets are used to treat gastric.
  • Doctors advise patients to chew the tablet instead of swallowing.
  • Breaking up the tablet into smaller pieces increases the total surface area exposed and increases the rate of reaction between the medicine and the acid in the stomach.
Cooking Food
  • Potatoes are cut into thin slices or long strips so that it can be cooked faster.
  • Thin slices or long strips increases the total surface area exposed to the cooking oil compared to uncut potatoes.
  
Concentration Factor
Corrosion due to Acid Rain
  • Buildings made of iron that are located near the industrial areas will corrode fast due to acid rain.
  • The atmosphere around industrial areas contains a high concentration of sulphur dioxide.
  • When the concentration of the acidic pollutants increases, the level of acid rain increases and the rate of corrosion increases.
Combustion of Petrol in Car Engines
  • Petrol vapour and air are compressed in the car engine combustion chamber before being burned.
  • The compression increases the concentration of the petrol vapour allowing the petrol to burn very quickly until it explodes.
  • The energy released from the combustion of petrol will make the car move.
 
Temperature Factor
Cleaning
  • Washing clothes using detergent powder and hot water combines two factors that increase the rate of reaction.
  • The process of washing clothes will be even quicker in this situation.
Cooking Food
  • Other than decreasing the size, food also cooks faster at high temperatures.
  • Water boils at 100 °C while cooking oil would not boil even the temperature reaches 180 °C.
  • Therefore, frying food in oil will cook the food even faster
 
Catalyst Factor
Catalytic Converter
  • Modern cars are fitted with catalytic converters to cut down atmospheric pollution.
  • Exhaust gas from car engines contains pollutants.
Making Alcohol
  • Ethanol, C2 H5 OH, is the main ingredient in alcoholic drinks.
  • Ethanol is produced through the fermentation of glucose with the help of enzyme in yeast as a catalyst at 37 °C.
