Aim:
To investigate what factors affect the rate of a chemical reaction.
Research and Variables:
Background information:
The rate of reaction is the speed of a chemical reaction. If the molecules combine at a slower speed this means the reaction has a slow rate. Therefore a reaction with a high rate has molecules that combine fast. Reaction times differ; they can be hundreds of years or even less than a second. The speed of the reaction is determined by the specific molecules that are being combined.
The speed of the reaction is determined by the specific molecules that are being combined. The collision theory states, that when more collisions occur there will be an increase in combinations of molecules rebounding off each other. If there is more molecules, than there is a higher chance that the molecules will complete the reaction. When all of this takes place it speeds up the rate of a reaction. An example of this is maple syrup the molecules move slowly compared with soft drink where they move fast.
Reactions are happening all the time no matter what. This is because chemicals are always breaking down or combining. Reactions happen continuously, but not always at the same rate.
Kinetic energy is related to the motion of an object which connects with rates of reactions. The faster an object moves the more kinetic energy it has. When something accelerates it gains kinetic energy. This is like when a gas’s temperature is increased it has more kinetic energy. Exothermic is a chemical re...

...ictures and observations and then we would all clean up and move onto the next rotation. As a group we worked extremely well doing our tasks and getting the job done professionally.

Conclusion:
Overall my aim from the experiment conducted was achieved as; the factors that affect the rate of a chemical reaction were discovered. My hypotheses were proven as; a catalyst increases the speed of a reaction, larger surface area have a faster reaction rate, additional stirs make the reaction occur faster, the higher concentration levels quicken the rate of a reaction and temperature speeds up the reaction time. The investigation was a fair test as all variables were controlled as my results support this. Although the practical activity could be improved if it was to be repeated. Altogether it was a fantastic learning experience that I am grateful for participating in.
