The Affect of Changing the Concentration on the Rate of Reaction :: Collision Theory Reaction Rates Essays

The Affect of Changing the Concentration on the regularise of ReactionTo find start the affect of changing the concentration on the rateof reactionScientific backgroundCollision theory Collision theory explains how chemical reactionsoccur and wherefore rates of reaction differ. For a reaction to occur,particles must collide. If the collision causes a chemical change itis referred to as a fruitful collision and its a surmisal that explainshow chemical reactions take place and why rates of reaction change?For a reaction to occur the reactant particles must collide. Only acertain share of the total collisions cause chemical change theseare called fruitful collisions. The fruitful collisions have enoughenergy (activation energy) at the moment of impact to break theexistent bonds and form new bonds, resulting in the products of thereaction. Increasing the concentration of the reactants and raisingthe temperature bring ab come forth more(prenominal) collisions and therefore morefruit ful collisions, increasing the rate of reaction.Rate of reaction amount of a substance that takes part in a chemicalreaction in a given time, and its also Finding out how quicklyreactions take place and understanding why they happen at the ratethey did.Molecules Molecules are compounds made up of atoms.Movement is how the reaction occursActivation capacity the minimum energy in the reaction.Prediction What I predict to happen in my experiment is that when Iadd 10 cm3 of Hydrochloric acid into the flask with the atomic number 11Thiosulphate of 50cm3 then I hypothesise that the cross will disappeara lot faster than when I add less amount of Hydrochloric acid.Hypothesis I predict is that when I use high concentration of Na2S2o3the rate of reaction would be very fast and the cross is going todisappear more apace and when the solution is more diluted by addingmore (water) so the reaction will slow down much slower and it willtake more time for the cross to disappear. I think this will happenbecause by adding more water in it will produce more particles in the tough solution so because of this there will be more collisionsand it will slow down the reaction.Apparatus In order to do any sheath of experiment, you need equipment.The equipment I will use isMeasuring CylinderSmall measuring cylinderFlask2 beakersPaper marked with a heavy(a) cross in the middle.Stops watch (Timer).Method- Firstly we got the equipments listed above- Then we set it up the equipment as shown above.- We got a piece of paper and force a big cross on it.- Then using a conical flask and 100ml beakers and a 250ml beaker we
