Once this The collision theory essay added start the timer. Finally, once the cross has completely disappeared stop the clock and make a not of the time it took for the mixture to become one.
The greater the surface area the higher the chance of collision and therefore the higher the chance of reactions as there is more room for the reaction to take place. Prediction There are more particles per volume in a more concentrated solution; therefore, there is a greater chance of collision, which means there shall be more collisions per second.
Acid Concentration molar Volume of 2. The following may have affected our experiment in one way. There is always a drastic increase in movement of the molecules that are given more energy. Draw a cross on a piece of paper and place a beaker on top of the paper.
The ribbon shall be spiralled. These measurements shall be accurately measured by using burettes. More reactants leads to more effective collisions between the particles to create a new product whereas a higher concentration of products is associated with a slower reaction rate.
I predict that if the concentration of the acid is doubled 1. This procedure was produced with different concentrations. I learnt how different quantities and temperature can affect the speed of collision with in the particles. A large piece of marble chip will have a smaller surface area than of four pieces that weigh the same as the large piece in total.
At a higher concentration collisions are again more frequent, as there are more reactant particles in the liquid. From the experiment we had a set of results these were: I know that the increased temperature increases the rate of reaction; therefore there is an increase in the particles colliding.
To control the problem of affecting results I would have to swirl the mixture for e. How to Write a Summary of an Article? Temperature is a measure of the average amount of kinetic energy in a system so a higher temperature leads to a higher average kinetic energy of the molecules in the reaction, therefore, more collisions occur; a faster rate of reaction.
The time it took till the clock was started and the difference between when "we" thought the cross was no longer visible. See figure 3 for further information.Open Document.

Show More. Decomposition of sodium thiosulphate Aim: Reaction rates are explained by the collision theory. The collision theory is.
The Collision Theory states that for two substances to react they must first collide. This means that in a higher concentration, there shall be more collisions because the ratio of reactants will increase, thus increasing the frequency of collisions.

Get started now! This essay has been submitted by a student. This is not an example of the work written by our professional essay writers. Some reactions are slow, and some reactions are fast, it depends on the rate of reaction. The collision Theory helps to explain 2 things: It helps explain how chemical reactions occur.Download
