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 will change when a catalyst is added to a chemical reaction?
When a catalyst is added to a chemical reaction, the rate of the reaction will increase without being consumed in the process. This means that the reaction will reach equilibrium faster and require less activation energy. The overall chemical equilibrium and products formed will remain the same.
The process of rapid combustion?
Rapid combustion is the fast chemical reaction between oxygen and a combustible material, resulting in the release of heat and light. This process is what we commonly refer to as fire. Factors such as the presence of fuel, oxygen, and heat, as well as the combustion process itself, all play a role in how quickly the combustion occurs.
What drugs can increase the speed of reaction?
Stimulants like amphetamines and caffeine can increase the speed of reaction by enhancing alertness and cognitive function. These drugs can improve performance in tasks requiring quick reactions and decision-making. However, it is important to use them responsibly and be aware of potential side effects and risks.
Does glucose increases the speed of chemical reaction?
Glucose can act as a substrate for biological reactions, but it does not inherently increase the speed of chemical reactions. The rate of a chemical reaction is determined by factors such as temperature, concentration of reactants, and presence of catalysts.
How does average particle speed affect the reaction rate?
As the speed of the particles increase, it causes them to collide with the other particles in which they are reacting with more frequently, increasing the reaction rate.
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 is the effect of increasing the concentration of enzymes in a reaction?
If the reaction speed has not already peaked, then it will increase
What a does a temperature increase cause the rate of a reaction to increase?
An increase in temperature typically causes the rate of a reaction to increase because it provides more energy to reactant molecules, allowing them to collide with greater force and frequency. This often leads to more successful collisions and faster conversion of reactants to products.
What does a temperature increase cause the rate of a reaction to increase?
As temperature increase the speed and energy of molecules increase and the collisions are more probable.
How does a enzyme increase the speed of a reaction?
The enzyme reduces the activation energy of the reaction, therefore chemical reaction speeds are increased.
Does the core cause a huge increase in the speed of P-waves?
No, it causes a huge decrease in speed.
What causes speed to increase or decrease?
Presence of friction, incline and so on.
Catalysts speed chemical reactions but are not change by them?
True. A catalysts job is to increase the rate of reaction, but it must do so without (a) being changed by the reaction or (b) become incorporated into the final product.
Why does increased temperature speed up a reaction?
The motion of chemical entities increase with the temperature and the probability of collisions also increase.
What effects does temperature have on chemical changes?
Generally the speed of reaction increase when the temperature is increased.
Why is a catalyst needed in the body?
To increase the speed of the metabolic reaction taking place in our body
