Chemistry

I can see from my results that temperature does seem to have an effect on the rate of reaction.
With lower temperatures, the time taken for the cross to disappear was greater because the particles do not have as much energy as they did with higher temperatures, so they collide more infrequently.
I think that the experiment was successful and the times obtained are reasonably reliable.
From the results table I can see that at every time the temperature increases the time taken more or less halves. If I had a chance to re-do one of the reactions I would plan to change the 15-20* results because it does not quite fit in with the trend of the other results.
If I were to restart the investigation I would improve the measuring out of reactants because I did not think this was accurate enough each time.
I think the results overall are reliable and are able to support a conclusion – the only result that is slightly anomalous is the time obtained from 15-20*c
If I was to suggest anythin...
