- Changing temperature (heating increases speed of endothermic reactions and such reactions with a huge activation energy; cooling increases speed of exothermic reactions
- Adding a catalyst (makes the activation barrier smaller --> reaction faster)
- Vary the pressure. If there are less equivalents of gas molecules on product site than on educt site, pressure increase will increase reaction speed and vice versa.
- Changing concentration; if the educt concentration is increased or / and product concentration decreased (e.g. through destillation of the product), the reaction will go faster.
--> These four principles can found in the Le Chatelier - Sentence. Nice example is the Haber-Bosch synthesis.
What else can I help you with?
What are four ways that chemists control the rates of chemical reactions?
Increase in Surface area,Increase in temperature,Increase in concentration,and the presence of catalysts or inhibitors.
What are two ways the speed of a chemical reaction can be increased if both of the reactants are aqueous solutions?
The speed of a chemical reaction can be increased by increasing the temperature, as higher temperatures provide more kinetic energy to the reactant molecules, leading to more frequent and energetic collisions. Another way is to increase the concentration of the reactants, as a higher concentration provides more reactant particles in a given volume, increasing the likelihood of collisions and reactions.
What are two ways that chemical weathering changes rocks?
Physical and Chemical
What are 6 ways the number of effective collision in a chemical reaction can be controlled?
Increase concentration of the reactantsDecrease concentration of the productsAdd a catalystIncrease the temperatureIncrease the pressureStirOf course... do the opposite of these things if you are trying to slow it down.
What are two ways that chemical reaction between substances affect chemical bonds?

Name two ways in which friction can be increased?
Okay 2 ways for the friction to increase is speed and non lubricant
What are four ways that chemists can control chemical reactions?

What are the two ways to increase speed?
Two ways to increase speed are improving physical fitness through strength and conditioning training, and improving technique and form through practice and coaching. Additionally, focusing on proper nutrition and recovery can also help improve speed performance.
What are two ways that water may increase the rate of weathering?
Water can increase weathering rates by physically breaking down rocks through freeze-thaw cycles or chemical weathering processes like dissolution where water reacts with minerals to break them down. Additionally, water can carry dissolved ions that speed up chemical reactions leading to faster weathering of rocks.
What speeds up in chemical reaction?
There are numerous ways to affect the speed of a chemical reaction. They are add a catalyst, increase the concentration of reactants, increase surface area of reactants, increase pressure, and increase the energy in the environment around the reaction.
What are 2 ways to increase kinetic energy?
Increasing the speed of an object or increasing its mass are two ways to increase its kinetic energy. Additionally, changing the direction of motion can also result in an increase in kinetic energy.
What are two different ways to change drag on an airplane and how would the airplane respond to that?
Flaps would increase drag increasing your speed will increase it even more
What is the best way to increase speed without sprinting?
since there is friction the thing that is touching the ground will be pushing off that and will gain acceleration which will give you speed
What are 3 ways something can accelerate?
Three ways something can accelerate are 1. increase speed 2. change direction 3. both.
How do you increase the speed of the pump?
There are 2 ways:-By increasing the intensity of the current flowing to the pump.By increasing the number of turns in the coil.
