- surface area of a solid reactant.
- concentration or pressure of a reactant.
- temperature.
- nature of the reactants.
- presence/absence of a catalyst.
What are 5 factors that affect the rate of a chemical reaction?
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 3 factors that affect the rate of chemical reaction?
The rate of a chemical reaction is influenced by many different factors, including
reactant concentration, surface area, temperature, and catalysts
.
What are the different factors affecting the rate of a chemical reaction explain any 3 with the help of relevant examples?
- Reactant concentration.
- Reaction temperature.
- Nature of reactants and products.
- Presence of a catalyst.
- Surface area.
- Radiation exposure.
What are the three factors affecting the rate of a reaction that you will be testing in this lab?
The rate of a chemical reaction depends on a number of factors:
temperature, particle size (surface area), concentrations of reactants, nature of the reactants, and the presence of a catalyst
.
What are factors affecting rate?
- temperature.
- concentration.
- particle size.
- use 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.
What are the 4 factors affecting the rate of reaction?
- surface area of a solid reactant.
- concentration or pressure of a reactant.
- temperature.
- nature of the reactants.
- presence/absence 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 are the factors that affect rate of chemical reaction?
- 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 factor does not affect rate of reaction?
Nature and concentration of the reactants and temperature of the reaction influence the rate of reaction. But
molecularity
does not affect the rate of reaction as it includes the number of atoms, ions or molecules that must collide with one another to result into a chemical reaction.
What does not affect rate of reaction?
So if you have a reaction order of Zero (i.e., s+t=0), this basically means that
the concentration of the reactants
does not affect the rate of reaction. You could remove or add reactants to the mixture but the rate will not change.
What is precipitate give example?
A precipitate is a solid that forms out of solution. A common example is that of the mixing of two clear solutions:
Silver nitrate (AgNO3)
and sodium chloride (NaCl): AgNO3(aq)+NaCl(aq)→AgCl(s)↓+NaNO3(aq) The precipitate forms because the solid (AgCl) is insoluble in water.
Does pH affect reaction rate?
The rate of chemical reactions
can be altered
by changing pH, temperature, and/or the substrate concentration. … Optimal pH increases enzyme rate of reaction while less than optimal pH decreases it.
What would speed up a reaction?
- The concentration of the reactants. The more concentrated the faster the rate.
- Temperature. Usually reactions speed up with increasing temperature.
- Physical state of reactants. …
- The presence (and concentration/physical form) of a catalyst (or inhibitor). …
- Light.
Which factor would slow 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.
