What are everyday examples of temperature effects on reaction rate?
- Could you give me an example in our daily life which shows that reaction rate is depending on temperature and concentration?
Here are just a few everyday demonstrations that temperature changes the rate of chemical reaction:
Increasing the concentration of reactants also changes reaction
- Cookies bake faster at higher temperatures.
- Bread dough rises more quickly in a warm place than in a cool one.
- Low body temperatures slow down metabolism. In fact, warm-blooded animals regulate
body temperature so that their biochemical reactions run at the correct rate.
- Lightsticks produce light via a chemical reaction. Dropping a lightstick into hot water makes it glow more intensely, demonstrating that the reaction runs faster
at higher temperature.
- Two antacid tablets will neutralize a given amount of acid faster than one tablet will.
- Higher concentrations of acid in rain erode marble faster than lower concentrations.
