* The equation for the rate of reaction is 1/time.

* The rate of reaction measures the speed of reaction. It is a measure of the loss of reactants and gain of products.

* The faster a reaction takes place, the shorter the time needed for the reaction to finish.

* An example of a slow reaction is rusting

* An example of a fast reaction is sodium and water.

This predicts what will happen to the speed of a reaction if a variable like surface area, concentration and temperature. This theory says that when particles collide a reaction occurs.

* With a greater surface area a solid, particles collide far more frequently and as a result the reaction rate is greater.

* If there is a higher concentration the particles are closer and they have a greater chance of colliding. The more collisions, the faster the reaction.

* The higher the temperature the faster the particles are going to move. This means that there are many energetic collisions that will speed up the reaction.

* Plot a graph to show the results you found during this investigation.

The results clearly demonstrate that a higher volume of sodium thiosulphate will give a faster reaction time. When the volume of water is higher the reaction is slower. I will use the same values as above but I will add values in between, as I feel that this will increase the accuracy of my experiment and will enable me to have a greater range of numbers and will produce more definite results.

* Repeat three times and take an average. Record the results
