Do catalysts decrease or increase energy required to begin a reaction?
Catalysts decrease activation energy.
Does a catalyst decrease or increase the activation energy required?
The catalyst decrease the needed activation energy.
Latent heat of vaporisation decreases as pressure increases and becomes zoro at critical pressure i read . why it so?
As pressure increases the temperature required to vaporize water is less. So with increase in pressure there is decrease in temperature required to boil so latent heat also decreases.
Why does a catalyst speed up the rate of reaction?
The use of a catalyst increases the chance of particles meeting. This causes there to be a decrease in activation energy, and results in an increase in rate of reaction.
What are the 2 reasons why a decrease in temperature slows a chemical reaction?
Decreasing the temperature reduces the kinetic energy of the molecules involved. This means that fewer molecules have the activation energy required to actually react. It also means that molecules will collide less often.
Do catalysts decrease or increase energy required to begin a reaction?
Catalysts decrease activation energy.
Why does an increase in reaction temperature generally increase the reaction rate?
All chemical reactions must be thought of as collisions between the particles of reactants and products. As the temperature of the reaction increases, the energy of the particles also increases and so there is a greater chance of more collisions occuring, and as a result, in general, an increase in reaction temperature increases the reaction rate
Do enzymes increase the activation energy of biochemical reactions?
Enzymes speed up a chemical reaction by lowering the energy required for a reaction to procede, the Activation Energy (Ea). The overall change in energy of the reaction is unchanged, so the net amount of energy released in a reaction is not increased.
Does a catalyst decrease or increase the activation energy required?
The catalyst decrease the needed activation energy.
Latent heat of vaporisation decreases as pressure increases and becomes zoro at critical pressure i read . why it so?
As pressure increases the temperature required to vaporize water is less. So with increase in pressure there is decrease in temperature required to boil so latent heat also decreases.
How is temperature related to a chemical reaction rate?
Ignition temperature is the temperature a substance needs to reach before it is combustible. Activation energy is the energy required to start a reaction occurring. Temperature is directly affected by heat. Heat is a form of energy. Therefore as you add energy to a substance it heats up. It will reach its ignition temperature and combust. The combustion is the reaction.
Why does a catalyst speed up the rate of reaction?
The use of a catalyst increases the chance of particles meeting. This causes there to be a decrease in activation energy, and results in an increase in rate of reaction.
Would the money supply increase or decrease if the required reserve ratio was lowered from 20 percent to 10 percent?
That would be decrease
What are the 2 reasons why a decrease in temperature slows a chemical reaction?
Decreasing the temperature reduces the kinetic energy of the molecules involved. This means that fewer molecules have the activation energy required to actually react. It also means that molecules will collide less often.
How does a catalyst speed a reaction at low temperature?
A catalyst reduces the amount of energy required to produce the reaction. This speeds up the reaction and causes it to finish more quickly. Raising the temperature will also speed up a reaction.
Is esterification exothermic or endothermic?
endothermic reaction. because as you may have seen, high temperatures are required to speed up the reaction. this is because, since the reaction in endothermic, high temperatures would cause the equilibrium to shift forward to decrease the temperature thus leading to the formation of more esters thereby speeding up the reaction (le chatelier's principle).
Which of the following can the Fed accomplish by raising or lowering the required reserve ratio?
Increase or decrease the money supply
