Rate of reactions are used in many things in daily life. For example;
- Enzymes:
Enzymes are biological catalysts (substances with increase the rate of reactions). They quicken the rate at which food is broken down.
- Washing Clothes:
Temperature affects the rate of reactions. The higher the temperature the quicker the particles move. If they move quicker there is a bigger chance that they will collide (search the collision theory). This is why the temperature at which clothes are washed is important. There are enzymes in washing powder. They work well at a certain temperature, but when the temperature gets too hot, they do not work. The proteins that make up the enzyme are "denatured". (search how enzymes work)
- Fridges
Again, at a lower temperature the rate of reaction is less. So in a fridge reactions happen slower so foods rot slower (as rotting is also a chemical reaction)
Hope this helps! I looked on the internet for this question too, but it doesn't help. I found these answers in the Chemistry for You book by Lawrie Ryan. They're really useful.
What else can I help you with?
Why are reaction rates important?
This is really important and it boils down simply to safety. Having control over the rates of reactions, especially exothermic reactions such as polymerization, can ensure the adequate production of your desired product, such as polystyrene, but can also ensure that the people working within the area of the reactor are protected from pain that could result if reaction rates were not monitored. A lot of things would blow up and a lot of lives could be at risk.
Why do chemists need to know the factors that affect reaction rates?
It is important to control chemical reactions in industry.
What reaction rates do not tell you how fast?
Reaction rates do not provide information about the mechanism of a reaction, the pathway taken by the reaction, or the individual steps involved in the process. Additionally, reaction rates do not give details about the concentration of reactants or products at different points during the reaction.
Which of the following statements is true Chemical reaction rates vary with the conditions of the change but nuclear rates do not Nuclear decay rates vary with the condition?
Nuclear decay rates do not vary with the conditions of the change; they are constant for a given isotope. On the other hand, chemical reaction rates can vary with conditions such as temperature, pressure, and the presence of catalysts.
How are reaction rates used in medicine?
Reaction rates are used in medicine to understand how quickly a drug is metabolized in the body, which helps in determining dosage and frequency of administration. They are also important in studying the rate of enzyme-catalyzed reactions in the body, helping to design more effective enzyme inhibitors for therapeutic purposes. Additionally, reaction rates play a role in pharmacokinetics, which helps in predicting how long a drug will remain in the body at effective levels.

What will not affect reaction rates?
Astrological signs will not affect reaction rates.
What is the significance of the Arrhenius prefactor in the calculation of reaction rates?
The Arrhenius prefactor is important in calculating reaction rates because it represents the frequency of molecular collisions that lead to a chemical reaction. It accounts for the likelihood of successful collisions between reactant molecules, influencing the overall rate of the reaction.
How does physical states relate to reaction rates?
The reaction rates are higher in gases.
What is the importance of reaction rate?
As the reaction proceeds the concentrations of the reagents are not known. However, at the start of the reaction the initial concentration of the reagents IS known. Any orders that are calculated from average rates may not take into account such factors as autocatalysis or any mechanistic change due to concentration effects. Initial rates allow more reliable information to be determined regarding orders, activation energies and possible mechanisms (which is the ultimate aim of reaction kinetics)

What is the purpose of an inhibitor in a chemical reaction?
An inhibitor is used in a chemical reaction to slow down or prevent the reaction from occurring at a normal rate. It does this by interfering with the chemical process, usually by blocking or disrupting key steps in the reaction pathway. This can be useful for controlling reaction rates or minimizing side reactions in a desired chemical process.
How nuclear decay rates different from chemical reaction rates?
nuclear decay rates take more time and chemical reaction rates could happen fast.
What reaction rates do not tell you how fast?
Reaction rates do not provide information about the mechanism of a reaction, the pathway taken by the reaction, or the individual steps involved in the process. Additionally, reaction rates do not give details about the concentration of reactants or products at different points during the reaction.
Where can one find information on daily mortgage rates?
There are many places where one can find information of daily mortgage rates. The best place to find information on daily mortgage rates is a bank or other financial institution.
What is the significance of controlling the keyword density of gas mixtures in industrial processes?
Controlling the keyword density of gas mixtures in industrial processes is important because it affects the efficiency and effectiveness of the process. By adjusting the ratio of different gases in the mixture, manufacturers can optimize the reaction rates, product quality, and overall performance of the industrial process. This helps in achieving desired outcomes, reducing waste, and improving the overall productivity of the operation.
