Temperature of system (molecular vibrational speed), Pressure of system (proximity), Catalysts (lowers activation energy of reaction), Volume of vessel (related to pressure), and Concentration of reagents (more collisions).

∙ 9y agoFactors influencing the rate of a chemical reaction include the concentration, physical state, and dispersion of reactants. Further factors include the temperature of reactants, along with the type of solvent and catalyst used.

∙ 12y agothis is probaly a gcse or equivelant level question and as such i will not go into to much detail. the primary factors affecting the rate of reaction are; temperature concentration surface area of reactants the presence of a catalyst purity of reactants and somtimes stirring
Wiki User
∙ 12y agoThe surface area of the reactants (more area is faster), the temperature of the reactants (colder is slower), pressure of the reactants( depending on the product is how this effects this) I believe there is more but can't think of them at the moment

∙ 11y agoThe basic things that affect reaction rate are:
Temperature - as temperature goes up, reaction rate goes up. This is a result of the fact that temperature is a measure of the kinetic energy of the particles of a substance. Increase the temperature, and you increase how fast their particles are moving and colliding with each other, which better facilitates a chemical reaction.
Pressure - under increased pressure, reaction rate also goes up. This makes sense when you think about it, since increased pressure means increased temperature (according to the Gas Laws.)
Concentration - solutions with a higher concentration of reactant will cause a reaction to happen quicker, simply because there's more of it to work with.
Catalyst - the presence of a catalyst can speed up a reaction. A catalyst is a substance that doesn't participate chemically in the reaction, but lowers the required activation energy, making the reaction easier to happen.

What 4 factors increase a reaction rate?
4 factors that affect reaction rate are Temperature, Stirring, Concentration, and Pressure (only for gases).
Which of these factors will not affect reaction rates?
The proper term for the phenomenon of reaction rates is known as chemical kinetics. Generally for any chemical reaction factors such as temperature, concentration, pressure, physical state, presence of a catalyst, and the reaction rate order. Reaction rate order is specific for each chemical reaction. So to sum it all up, if you influence the environment in a manner that does not change one of these listed variables, then it will not likely do anything to a reaction rate. But to be honest, I can't think of a single thing you could do to a reaction that wouldn't influence one or more of these parameters.
How does increasing pressure affect the reaction rate?
The concentration of reactants is changed.
What are three factors that affect the rate at which a substance dissolves?
temperature,chemical composition.
Which factors must be equal in a reversible chemical reaction at equilibrium?
the rate of te forward reaction and the rate of the reverse reaction
What are the factors affecting the rates of chemical reaction in pollution?
The factors that affect in the rate of chemical reaction are temperature and YOU XD HAHAHAHAHAHAHAHA jk
How does an increase in temperatre affect chemical reaction?
Increases reaction rate.
How does concentration affect the rate of a chemical reaction?
Increasing the concentration of the reactants increases the rate of the reaction.
What are the 5 factors that can affect the rate of chemical reactions?
5 factors that can affect the rate of chemical reactions are temperature, pressure, concentration, stirring, catalysts.
What 4 factors increase a reaction rate?
4 factors that affect reaction rate are Temperature, Stirring, Concentration, and Pressure (only for gases).
How does temperature affect the rate of a chemical change?
Changing temperatures has a dramatic affect on the rate of chemical reaction. As an example for every 10 degrees you raise the environment the reaction doubles (to a certain degree)
How is a catalysts different from a reactant?
a catalyst can affect the rate of a reaction. speeding it up.

Do emzymes increase the rate of chemical reaction they affect?
That is precisely correct.
What do concentration surface area and temperature have in common?
They can all affect the rate of a chemical reaction.
How does the amount of time given affect the rate of the enzymatic reaction?
it will increase the time of the chemical reaction
How does the reaction temperature affect the rate of a chemical reaction?
Changing temperatures has a dramatic affect on the rate of chemical reaction. As an example for every 10 degrees you raise the environment the reaction doubles (to a certain degree)
