Above Time Vs Temperature Essay

The above Time Vs. Temperature graph displays the results of an experiment measuring the time taken for a sodium thiosulphate solution, at a certain temperature, to react with Hydrochloric acid. The descending curve in the above graphs suggests that the higher the temperature of the sodium thiosulfate solution the faster the reaction, causing the cluster of data later on in the graph. This is due to the high temperatures causing the increase in the particles average kinetic energy, the more energy provided by the heat of the water baths the faster the particle within the solution are able to move. As a result of the increased movement the particles are more likely to collide in the correct orientation and cause a faster reaction to occur. As the temperature reaches room temperature, moving from right to left of the graph, the reaction time …show more content…
Within this practical there were many possibilities for systematic errors to occur, one of these being the accuracy of the equipment used. This experiment was based heavily on the use of a variety of apparatuses including thermometers, water baths, beackers etc. and relies on the exactitude of this equipment to gain accurate results each time. It is possible that the water baths used to heat the thiosulfate solution were not working correctly i.e. a 40°C bath could not reach 40°C, usually this would not be an issue due to the temperature being monitored by a thermometer although if this apparatus was also not working properly it would make it very difficult for accurate temperatures to be recoded especially if both pieces of equipment were inaccurate. This would affect the results by using inaccurate values that are either too low or too high. If the values were too low it would not show as much of a dramatic result in the graphs as it should and affect the idea that higher temperature will mean a faster
