Is a substance that increases the rate of a chemical reaction.?
Factors affecting the reaction rate: - Concentrations of the reactants- Temperature- Pressure- Stirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
What affects how fast a chemical reaction takes place?
The nature of the reactants, the temperature (and pressure if gases are involved), and the presence of a catalyst.
What are different factors that affect the rates of chemical reactions?
Some different factors that affect the rates of chemical reactions include whether or not a catalyst is present, the concentration of the reactants, temperature of the reactants, & pressure in the case of gas phase reactions.
How are rates of reaction determine?
5 factors that can affect the rate of chemical reactions are temperature, pressure, concentration, stirring, catalysts, etc.
What happens to catalyst in a reaction?
it is incorporated into the reactants
What factors can influence the rate of reaction?
Concentration of reactants and time; also: temperature, pressure, stirring, added catalyst, the type of solvent, surface area of reactants, effect of other physical factors as irradiation, etc.
What effects the rate of reaction?
1.concentration of reactants 2.temperature 3.nature of reactants 4.presence of catalyst 5.surface area of reactants 6.radiation
What are three factors of the speed at which a chemical reaction happens?
temperature presence or absence of a catalyst concentration of reactants
What is the difference between a homogeneous catalyst and a heterogeneous catalyst?
The difference between a homogeneous and a heterogeneous catalyst is that in a heterogeneous catalyst, it is in a different phase from the reactants. However, in a homogeneous catalyst, it is in the same phase as the reactants.

Which methods will usually cause a reaction to speed up?
Combining the reactants at a lower temperature. Reducing the concentration of reactants. Grinding one of the reactants into a powder. Removing the catalyst.
What factor does affect the most rate of reaction?
Factors affecting the rate of reaction 1. Temperature 2. Catalyst 3. Concentrations of the reactants 4. Nature of the reactants 5. Surface area of the reactants
What are the 5 important factors that influence the rate of a chemical reaction?
Temperature Surface area/phase of reactants Concentration of reactants Presence of catalyst Activation energy of reaction
What are four factors which affect the rate of chemical reaction?
Temperature, atmospheric pressure (normal circumstances would be 1atm), percentage uncertainty of the equipment, loss of heat to your surroundings, parallax when reading scales such as a thermometer. And basically any variables that can be changed to be more accurate e.g your using cm's instead of mm's. Hope that helps :)
What affects how fast a chemical reaction takes place?
The nature of the reactants, the temperature (and pressure if gases are involved), and the presence of a catalyst.
What are the reactants of a catalyst-assisted reaction?
Reactants are also known as substrates.
What are different factors that affect the rates of chemical reactions?
Some different factors that affect the rates of chemical reactions include whether or not a catalyst is present, the concentration of the reactants, temperature of the reactants, & pressure in the case of gas phase reactions.
