The Effect of Temperature on the Rate of a Chemical Reaction

The Effect of Temperature on the Rate of a Chemical Reaction Aim:

In this investigation we are trying to find out how the temperature

affects the rate of reaction.

Hypothesis:

I believe that the higher the temperature, the faster the reaction the

reaction between the sodium thiosulphate and hydrochloric acid. This

will happen because kinetic energy and the heat energy makes the

particles move faster, collide faster and react faster; therefore they

can break bonds easier.

Scientific Knowledge:

Firstly, I will explain the equation needed to follow out the

experiment:

[IMAGE]Na2 S2O 3(aq) + 2HCL(aq) 2NaCl(aq) +SO2 (g)+ H2O (l)+S(s)

This is the experiment that will carried out, I will now put this

equation into word format:

Sodium Hydrochloric Sodium Sulphur

[IMAGE]Thiosulphate+ Acid Chloride+ Dioxide + Water + Sulphur

The sodium thiosulphate consists of: two atoms of sodium, two atoms of

sulphur and two atoms of oxygen. This combined with the hydrochloric

acid creates a chemical reaction and the products are 2 molecules of

sodium chloride, a molecule of sulphur dioxide, water and sulphur.

Rate of reaction:

The rate of reaction is the speed or velocity at which a chemical
