Introduction

Lewis Brend Friday. 28 September 2001 Rates of Reaction Aim: To find out how temperature will effect the rate of reaction between sodium thiosulphate and hydrochloric acid. Apparatus: Stop-clock Conical flask Thermometer Beaker Tripod Gauze Bunsen Burner Paper with a cross on it Safety Specs Heat Mat Measuring Cylinders Sodium Thiosulphate Hydrochloric Acid Prediction: My prediction is that the ...read more.

Middle

Light the Bunsen burner and fill a beaker with 100ml of water, then measure 20ml in a measuring cylinder and put into a conical flask. Put the conical flask in with the beaker. Keep checking the temperature by using a thermometer. ...read more.

Conclusion

Once it has gone this colour stop the sop-clock and take note of the time. Then do this for the rest of the temperatures. This will be made a fair test by not stirring the acids and by doing the exact same procedure to the other tests. Doing this will make it a fair test. Results: Temperature Time Taken 20� 131.16 30� 82.63 40� 31.02 50� 31.16 60� 24.55 70� 15.95 ...read more.

    The movement away of the electrons from the O - H bond makes the hydrogen molecule fall off comparatively more easier than the other acids. Hydrochloric acid is the next easiest molecule to break down, and has the next lowest activation energy.

The reason I think that this will happen is because, in a reaction particles collide to give the end results of the reaction.
