Five factors typically affecting the rates of chemical reactions will be explored in this section:
the chemical nature of the reacting substances
, the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration of the reactants, and the …
What are the factors that affect the rate of chemical reaction?
- surface area of a solid reactant.
- concentration or pressure of a reactant.
- temperature.
- nature of the reactants.
- presence/absence of a catalyst.
What are five factors that affect the rate of a chemical reaction quizlet?
- Nature of Reactants.
- Surface Area (more = faster)
- Temperature (higher = faster)
- Concentration (larger = faster)
- Catalyst (present = faster)
What are the 5 ways to change the rate of a chemical reaction?
- The concentration of the reactants. The more concentrated the faster the rate.
- Temperature. …
- Physical state of reactants. …
- The presence (and concentration/physical form) of a catalyst (or inhibitor). …
- Light.
What are the 5 factors that affect the rate of chemical reaction and give example for each?
- Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. …
- Physical state of the reactants and surface area. …
- Temperature. …
- Presence of a catalyst.
Which condition will increase the rate of chemical reaction?
Temperature
. An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure.
What three factors affect the rate of reaction?
Factors that influence the reaction rates of chemical reactions include
the concentration of reactants, temperature, the physical state of reactants and their dispersion, the solvent, and the presence of a catalyst
.
What are the six factors that affect the rate of reaction?
- Concentration of reactants.
- Pressure.
- Temperature.
- Catalyst.
- Nature of reactants.
- Orientation of reacting species.
- Surface area.
- Intensity of light.
Which factor that would not affect the rate of chemical reaction?
Answer:
Amount of product
does not affect reaction rate as the concentration of product do not appear in the rate law expression.
What slows down a chemical reaction?
To slow down a reaction, you need to do the opposite. Factors that can affect rates of reactions include surface area, temperature, concentration, and the presence of
catalysts
and inhibitors. Temperature – Changing the temperature of a chemical reaction also affects the reaction rate.
Which will increase the rate of a chemical reaction quizlet?
Describe three ways to increase the rate of a chemical reaction.
increase temperature by adding heat, increases the surface area of the reactants
, increase the concentration of the reactants, or add a catalyst. You just studied 4 terms!
Which conditions will increase the rate of a chemical reaction quizlet?
The rate of reaction increases
as concentration and temperature increases
. High concentration leads to more collision probability and higher temperature provides more kinetic energy for effective collisions.
What factors could be used to increase reaction rate quizlet?
Increasing the temperature
increases the rate of reaction because the particles collide more often and with more energy. The higher the temperature, the faster the rate of a reaction will be. If the concentration of reactants is increased, there are more reactant particles moving together.
How can you speed up a reaction?
- Increase the temperature in Endothermic reactions (Reactions that absorb energy, or become cold)
- Decrease the temperature in Exothermic reactions (Reactions that release energy, or become hot)
- Add a catalyst (A substance that reduces activation energy, speeding up the reaction)
What makes a reaction faster?
If you increase the concentration of a reactant, there will be more of the chemical present. More reactant particles moving together allow more collisions to happen and so the reaction rate is increased.
The higher the concentration of reactants
, the faster the rate of a reaction will be.
What are 3 ways to increase the rate of a reaction?
- There are 4 methods by which you can increase the rate of a reaction:
- Increase the concentration of a reactant.
- Increase the temperature of the reactants.
- Increase the surface area of a reactant.
- Add a catalyst to the reaction.
