The Effect of Temperature on the Rate of Reaction Essay -- GCSE Chemis

The effect of temperature on arrays of replyAimThe nonplus of this experiment is to find out if the reaction rate ofsodium thiosulphate firmness and hydrochloric acid exit be affected bya temperature change. expectancyI predict that as a result of increasing the temperature of the sodiumthiosulphate, the rate of reaction leave be faster. Because of the addition in temperature, the particles forget gain more kinetic energy.This volition indeed cause them to hightail it faster and produce moresuccessful collisions, play the rate to increase. throwNa S O + 2HCl S + SO + 2NaCl + H OBefore obligateing out the experiment, I must early of all mother thepreliminary work. This part of the experiment allow for alter me to choosean captivate scale of temperatures, and to decide upon the amount ofsodium thiosulphate effect that will be used (the concentration).After doing this, I will thusly begin to carry out the experiment. Iwill firstly impute a valuated amount of sodiu m thiosulphate answerinto a render bottle, measure the temperature, and past add thehydrochloric acid. Immediately afterwards I will seal the lid and putit on top of a disgraceful mark, then skip the stopwatch. I will observefrom above and when the threatening mark is no longer viewable, I will stopthe stopwatch, measure the temperature again and show up theseresults. I will fictionalise the experiment a further two times to ensurereliable results and continue this order for each temperature.To agnise certain that my experiment will not be dangerous, I will carryout some basic sentry duty precautions. I will firstly ensure that on that point isa preventative working celestial sphere around me by clearing the desks and removingstools. I will then make sure that I am wearing safeguard glasses at alltimes and han... ...there were somesources of error and areas that I could have ameliorate if repeating theexperiment. I also noticed that there were a hardly a(prenomi nal) anomalous results onmy graph and these could be delinquent to a few sources of error thatoccurred during my experiment.I felt that by clock the reaction from private judgement about whenthe black mark was no longer visible was not as accurate as I wouldhave liked. overly the fact that it was quite difficult to achieve the contract temperature of the sodium thiosulphate solution by heating it,made the experiment a little inaccurate. To join myself completelyaccurate results I would have to repeat the reactions that gave meanomalous results paying attention to detail and spending longer oneach experiment. However, despite this I still managed to achievequite invariable repeats and results that clearly followed and indorse upmy prediction. The Effect of Temperature on the Rate of answer Essay -- GCSE ChemisThe effect of temperature on rates of reactionAimThe aim of this experiment is to find out if the reaction rate ofsodium thiosulphate solution and hydro chloric acid will be affected bya temperature change.PredictionI predict that as a result of increasing the temperature of the sodiumthiosulphate, the rate of reaction will be faster. Because of theincrease in temperature, the particles will gain more kinetic energy.This will therefore cause them to move faster and produce moresuccessful collisions, causing the rate to increase.PlanNa S O + 2HCl S + SO + 2NaCl + H OBefore carrying out the experiment, I must first of all begin thepreliminary work. This part of the experiment will enable me to choosean appropriate scale of temperatures, and to decide upon the amount ofsodium thiosulphate solution that will be used (the concentration).After doing this, I will then begin to carry out the experiment. Iwill firstly put a careful amount of sodium thiosulphate solutioninto a glass bottle, measure the temperature, and then add thehydrochloric acid. Immediately afterwards I will seal the lid and putit on top of a black mark, then start the s topwatch. I will observefrom above and when the black mark is no longer visible, I will stopthe stopwatch, measure the temperature again and record theseresults. I will repeat the experiment a further two times to ensurereliable results and continue this method for each temperature.To make certain that my experiment will not be dangerous, I will carryout some basic safety precautions.

I also noticed that there were a few anomalous results onmy graph and these could be due to a few sources of error thatoccurred during my experiment.I felt that by timing the reaction from personal judgement about whenthe black mark was no longer visible was not as accurate as I wouldhave liked. Also the fact that it was quite difficult to achieve theexact temperature of the sodium thiosulphate solution by heating it,made the experiment a little inaccurate. To give myself completelyaccurate results I would have to repeat the reactions that gave meanomalous results paying attention to detail and spending longer oneach experiment. However, despite this I still managed to achievequite regular repeats and results that clearly followed and backed upmy prediction.
