Describe the collision theory in relation to reaction rate?
Eguzman5980
When you have a higher concentration of elements in the reaction you are no matter what speed going to have a faster reaction taking place however the lower the concentration it is the more time it will take for the reaction to take place this process is similar to pressure as it reflects how the more of it there is the faster the reaction will be and how if there is less of it the slower the reaction will be.

∙ 9y agoA faster reaction rate is caused by more collisions between particles of reactants. Chemical reactions happen because representative particles of substances collide with enough frequency and energy to facilitate a reaction. This is collision theory. If you increase the number of collisions and the energy with which they collide, you increase the amount of reactant used per unit time, which is reaction rate. The three best ways to do this are: increase kinetic energy (heat it up), increase concentration (add more stuff), and add a catalyst (another substance that speeds up the reaction by making it easier for more collisions to happen.)

How does collision theory relate to equilibrium?
Collision theory is when mollecules must collide with one another in order to cause a reaction. In a succesful collision, old bonds are broken as new bonds are formed. Equilibrium is a state in which forces cancel one another.
What happens when fast moving molecules touch?
If they collide hard enough, and have the right orientation, a reaction can take place. This is called collision theory, and it's a big part of kinetic molecular theory.
The collision theory states that in order for a reaction to occur the particles must come together and collide with each other with enough to break the bonds and form new ones?
pressure
Why does heat speed up a chemical reaction?
It provides energy to overcome the activation energy.
If the concentration of reactants is higher?
The rate of the forward reaction will increase if the concentration of the reactants is increased.This is explained by collision theory. When there are more molecules in a given space (a higher concentration) with the same energy, the molecules will collide more frequently, since they will move about randomly and are more likely to hit one another if there are more of them around and less empty space. A reaction requires a collision, so more collisions in a given amount of time will lead to more molecules reacting in that time, giving a higher rate of reaction overall (in the forward direction).
When talking about physical science what is the collision theory?
Collision theory is an instance of reaction kinetics. It serves as occurences of the topic map.
When will a collision lead to a chemical reaction?
When the collision is hard and fast enough. Increasing the kinetic energy will increase the likelihood of hard and fast collisions, which will ultimately increase the rate of the reaction. (This is called collision theory.)
What is collision theory?
The collision theory is when atoms, molecules or ions bash together or collide together. Collision theory states that the rate of a reaction may be increased by : increasing pressure; raising the amount of heat energy; raising the concentration of the reactant and by introducing a catalyst.

What is the collision theory and how does it relates to reaction rates?
it depends on how high or low the reactant is on the temperature.
How do catalysts affect collision theory?
A catalyst is a substance that increases the rate of a reaction without being used up. Some catalysts work by giving the the reacting particles a surface to stick to where they can make contact which increases the amount of collisions between the particles. Therefore a catalyst effects collision theory by speeding up a reaction.
Activated-complex theory of chemical kinetics?
actvated theory is just the collision theory but kinetic energy in activated comlex is less than collision theory
Use collision theory to explain why reactions should occur more slowly at lower temperatures?
Lowered temperature lowers reactants speeds, and decreased the number of low-energy collision, reaction rates decrees with a decrease in temperature.
Why does concentration of a reactant influence the reaction rate?
Oxygen!
What is Planetary Collision Theory?
The Collision Theory states that the rate of molecules colliding with sufficient kinetic energy successfully is proportional to the collision frequency multiplied by the fraction of collisions. The assumptions are that the molecules are spheres and traveling in straight lines.
Which two men proposed the collision theory?
The two men who proposed the collision theory are Max Trautx and William Lewis. The theory which was proposed in 1918 explains how chemical reactions occur.
What happens when fast moving molecules touch?
If they collide hard enough, and have the right orientation, a reaction can take place. This is called collision theory, and it's a big part of kinetic molecular theory.
