Reaction rate is increased most rapidly by:
- a- Humidity
- b- High temperature***
- c- Freezing
- d- Photolysis
- e- Hydrolysis.
The reaction rate is increased most rapidly by high temperature.
Temperature is a major factor that affects the reaction rate. According to the Arrhenius equation, the reaction rate increases exponentially with temperature. This is because high temperature increases the kinetic energy of the molecules, which makes them more likely to collide with each other and react.
The other options do not increase the reaction rate as rapidly as high temperature:
- Humidity can affect the reaction rate, but it is not as significant as temperature.
- Freezing can slow down or even stop a reaction.
- Photolysis and hydrolysis are both chemical reactions that can be affected by temperature, but they are not as sensitive to temperature as the overall reaction rate.
Here are some examples of how high temperature can increase the reaction rate:
- Cooking food:
Cooking food heats it up, which causes the chemical reactions that break down the food to occur more quickly.
- Digestion:
Digestion involves a series of chemical reactions that break down food into smaller molecules that can be absorbed by the body. These reactions occur more quickly when the body is warm.
- Engine combustion:
The combustion of gasoline in an engine is a chemical reaction that occurs more quickly at high temperature.
