rates of reaction

I want to investigate how temperature effects the rate of reaction

Equipment: A conical flask, beaker, measuring cylinders, stopwatch, black cross on paper, water, thiosulfate and hydrochloric acid is investigated

Method:

 1. Put X paper on the bench mat, and put the conical flask on top of the paper
2.  Measure 50ml of sodium thiosulfate solution and put it into the beaker
3. record the temperature of the sodium thiosulfate
4. Measure 5 HCL and pour this into the conical flask
5. Pour the sodium thiosulfate into the conical flask, start the stopwatch and swirl the flask. Time how long it takes for the cross to disappear when viewed from above (i.e look down the mouth of the flask)
6. Wash out the flask thoroughly
7. Repeat the experiment ,using a water bath to heat the sodium thiosulfate to 30c then 40c and finally 50c keep the volume of the acid the same each time


Conclusion

For collision to successfully occur there needs to be enough energy
