Investigate how temperature affects the amount of time it takes for a reaction to happen?

Preliminary work and research

The most important rule and theory in this project is the collision theory.

 (The following information I learnt from my teacher.)

"In order for a chemical reaction to occur, reactant particles must collide with sufficient energy to cause molecular rearrangement"

This collision is called a 'fruitful collision'

Any factor that affects the number of fruitful collisions will affect the rate of reaction.

Temperature, concentration, surface area and catalysts all affect the rate of reaction between two chemicals.

The factor I am concentrating on

The factor I will be concentrating on in this investigation is temperature.

If the temperature of a chemical is increased the particles have more energy so they move around faster and with more force.

This means there will be more collisions per second and the energy of the collisions will be greater.

Join now!

This means that there will be more fruitful collisions per second.

So: The hotter the substance: the more fruitful collisions there are: the faster the reaction takes place.

 Preliminary outline:

There are limits as to how much preliminary work can be carried out in this investigation.

I researched the subject carefully by reading books and looking on the internet but I also got an idea of how to carry out the experiment from my chemistry teacher.

Variables:                                        ...
