Rate of Reaction

Aim To find out how temperature affects the rate of reaction using a range of temperatures from 5oC to 55oC.

Prediction

A chemical reaction is where bonds break and atoms collide to form other substances.

I predict that as you raise the temperature the rate of reaction will increase.

The reaction occurs because two atoms and form a new substance.

The new chemical is different to the old one. More then two atoms can collide to make a new substance. A chemical change must occur. You start with one compound and turn it into another. That's an example of a chemical change. A steel garbage can rust. That rusting happens because the iron in the metal combines with oxygen in the atmosphere. Single reactions often happen as part of a larger series of reactions.

These are my preliminary results I based my prediction on these.

This informed my plan because it gave me a slight idea of what the results might look like and I know how to carry out the experiment.

I would know if the experiment were taking too long by judging the preliminary results.

I done the preliminary to see how I could do it better the next time I done the experiment

Sodium thiosulphate + Hydrochloric acid → Sulphur Dioxide + Sodium Chloride + Water
