The Effect of Catalyst an the Rate Of Reaction Essay -- GCSE Chemistry

The Effect of particle accelerator an the send Of ReactionChemistry Coursework Does The Number of Drops of Catalyst Effect The Rate Of ReactionCandidate Name Ben DoddsCandidate Number 7158 aim Oundle SchoolCompletion DateIntroductionWe are studying the reaction among zinc and sulphuric venereal infection, thereaction is catalysed by copper sulfate and this investigate is totest whether the amount of drops effect the rate of reaction.Word EquationZinc(s) + sulphuric acid(aq) Hydrogen(g) + Zinc Sulphate(aq)Symbol EquationZn + H2SO4 H + ZnSO4This reaction is catalysed by Copper sulphate (CuSO4)Ionic Equation - Cancel Spectator ion (SO42-)Zn + 2H+ Zn2+ + H2For this reaction to work thither must be hard collisions in the midst of thezinc and the hydrogen ions (acidity ion) from the acid, The faster theharder and the more often the collisions happen so I predict the morecatalyst the faster the reaction.Planning sentry go* Sulphuric acid at 2M is a corrosive substance moreover dil uted to 1M it is an Irritant, so wear a Lab coat to nurse your cloths and wear safety specs to protect your eye.* Zinc is very inflammable so do not put a Bunsen burner turn up it.* Copper sulphate is very nasty and corrosive when it gets in your eyes so wear safety specs.* Hydrogen is explosive when mixed with type O and burnt so dont use a Bunsen burner near the experiment. order======First a clamp stand was taken and a feature cyringe was fitted so thatwhen it is connected to a conicle flask the conicle flask will pushthe bench. 1 gram of zinc was taken along with 2M sulphuric acid anddistilled sollutions. The solutions were mixed to form 1 M acid and a accredited number of dfrops of catalyst wes added in the conicle flaskand the... ...zincand the amount of copper sulphatewere not kept constant.Did I do enough readingsI intend I have done enough readings as the trend of my predictionswere there but I could have done a greater range. The whole problemwith that is I woul d have to dilute the acid again as the times werevery quick for 15 seconds so it would be to fumbling to collect if Idid 30 drops of copper suphate it would have been to quick to record.Could your results hap to any findings outside the range of resultscovered?Yes I could as my interpret is a straight line graph so I could reach itand looking for at peradventure 40 or 50 drops and look at what the rate is for themWhat additional relevant work could you do to endure your theory?We chose to vary the amount of drops of catalyst but what you couldvary is maybe whether the temperature, pressure, concentration of theacid or amount of zinc.
