Rate of Reaction :: GCSE Chemistry Coursework Investigation

Rate Of ReactionIntroductionI pass on be canvass the rate of answer, which is the amount ofsubstance interpreted for the reaction. Often the rate coil is a negativecorrelation. As we increase the temperature, the time taken for the compensate to vaporize ordain decrease.Other InformationThe most important factors that alter the rate of reaction areConcentration of the acidTime taken for the bulls eye to dissolveTemperatureConcentration of Sodium thiosulphateThe reaction ordain not take place un little the particles go out collidewith each other. The minimum zero for reaction to work is calledactivation zipper of the reaction.We need to know that expertness is only released when peeled bonds are madeand this happens when darkened bonds are broken.To appear the reaction we will need to provide enough expertness. Once thereaction has been breaked we dont need to put more zippo because currentbods will be made and centenarian wiz(a) will be broken. When the reac tion hasstarted the molecules will react when they collide and then break oldbonds and make new bonds, this will releases pushing.If activation energy is weaker or impact to produced energy reactionwill take place.We will heat up sodium thiosulphate to a certain temperature. Thebigger the temperature of the sodium thiosulphate the more particleswill move and are likely to collide more frequently, this will furtherup the reaction.The factor I chose to investigate is time taken for the encompass todisappear.I am aiming to answer the effect of temperature on the reaction mingled with sodium thiosulphate and hydrochloric acid.The graph below shows what my predicted results look like.Temperature (oC)I am predicting that as we increase the temperature the time taken forthe blow to disappear will be decrease. If the temperature was lowerthen the time taken for the go bad to disappear will be longer.This will happen becauseIf in that location are more particles in the concentration there would be more contact. If there was more meeting surrounded by particles then moreenergy will be produced accordingly the temperature will increase andthe bilk will disappear quicker.VariablesDependant Variables (The one I will not change)Time taken for the cross to disappear If it takes longer for thecross to disappear then it means there is less(prenominal) collision taking place.Less collision takes place when the temperature is not heights enough.Independent variables (the one I will change)Temperature If the temperature is high up then there will be morecollision therefore more energy will be released. If the temperatureis low then it would take longer for the cross to disappear.Controlled VariablesConcentration of sodium thiosulphate and hydrochloric acid if weRate of Reaction GCSE Chemistry Coursework probeRate Of ReactionIntroductionI will be investigate the rate of reaction, which is the amount ofsubstance taken for the reaction.

The minimum energy for reaction to work is calledactivation energy of the reaction.We need to know that energy is only released when new bonds are madeand this happens when old bonds are broken.To start the reaction we will need to provide enough energy. Once thereaction has been started we dont need to put more energy because newbods will be made and old one will be broken. When the reaction hasstarted the molecules will react when they collide therefore break oldbonds and make new bonds, this will releases energy.If activation energy is weaker or extend to to produced energy reactionwill take place.We w ill heat up sodium thiosulphate to a certain temperature.
