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

The Affect of Changing the Concentration on the step of ReactionTo find out the affect of changing the concentration on the identifyof reactionScientific background encounter 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 Theory that explainshow chemical reactions conduct place and why rates of reaction change?For a reaction to occur the reactant particles must collide. Only acertain fraction of the nub collisions cause chemical change theseare called fruitful collisions. The fruitful collisions gravel enoughenergy (activation energy) at the moment of impact to break the actual bonds and form new bonds, resulting in the products of thereaction. Increasing the concentration of the reactants and raisingthe temperature act upon about much collisions and therefore to a greater extentfrui tful 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 in add onition Finding out how quicklyreactions take place and understanding why they happen at the ratethey did.Molecules Molecules are compounds made up of atoms. reason is how the reaction occursActivation Energy the minimum energy in the reaction. vaticination What I predict to happen in my experiment is that when Iadd 10 cm3 of Hydrochloric acid into the flask with the sodiumThiosulphate of 50cm3 then I theorize that the extend leave alone 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(prenominal) fast and the cross is going todisappear more rapidly and when the response is more diluted by addingmore (water) so the reaction will slow down much slower and it willtake more time for the cross to disa ppear. I think this will happenbecause by adding more water in it will produce more particles in theconcentrated solution so because of this there will be more collisionsand it will slow down the reaction.Apparatus In order to do any type of experiment, you need equipment.The equipment I will use is quantity CylinderSmall measuring cylinderFlask2 beakers melodic theme marked with a big cross in the middle.Stops stop (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 drew a big cross on it.- Then using a conical flask and 100ml beakers and a 250ml beaker we
