Effect of Temperature on the Rate of Reaction between Sodium Thiosulphate and Hydrochloric Acid :: GCSE Chemistry Coursework Investigation

Effect of Temperature on the Rate of Reaction between atomic number 11 Thiosulphate and Hydrochloric AcidInvestigationChemical fightions are used in our ordinary life, they literally keepus alive. They are used in food, ventilating system and everywhere else inthe environment. A chemical reply mainly occurs when reactantsreact together to produce a new crop. The speed at which thisreaction states place is called the place of reaction. The productproduced has a number of particles in the root word that has formedfrom the reactants. The concentration is the numerate of particles in acertain amount of water. If a cross is placed under the beaker of thesolution, the cross entrust finally disappear because the hightemperature of the water will make the particles move accelerated becausethey suffer more(prenominal) energy and they will move more quick to give a biggerimpact which will cause more frequent and violent collisions and thesolution will disappear as the product f orms to create a mistysolution. The rate of reaction is normally put down in tables and canthen be defined onto graphs to show how the rate wrenchs of differentfactors motivate the speed of the reaction. A rate curve is the curve ofa graph that shows how the reaction changes at different intervals.The gradient of the graph tells us whether the different rate curveshave the same relation, meaning if they have a similar rate ofreaction. Reactions can take place in a variety of customs they canbee steep or steady. The abrupt the slope, the faster the reactiontakes place. The steadier the slope, the slower the reaction takesplace.AimThe aim of my investigation is to find out whether the increase oftemperature increases the rate of reaction between the both reactantsof Sodium Thiosulphate and Hydrochloric acid. I will then find out and guess on how temperature affects this particular reaction.FactorsThere are four main factors, which affect the rate of reaction thatare considered a s variables for the investigate I will be doing, theyare the following Molecules can only collide when deuce of them meettogether. This meeting between the two particles can only take placeon the surface area of the natural. If the surface area of thematerial is increased, the particles gather more space to collide witheach other with force. With a large surface area, the particles willhave more area to bunk on so the collision probability will be high. Acatalyst is a separate substance to the ones you use in yourexperiment and is used to speed up the reaction between the reactants.
