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

The Effect of Catalyst an the Rate Of ReactionChemistry Coursework Does The government issue of Drops of Catalyst Effect The Rate Of Reaction prognosis Name Ben DoddsCandidate Number 7158School Oundle SchoolCompletion DateIntroductionWe ar studying the reaction between zinc and sulphuric acid, thereaction is catalysed by tomentum sulphate and this experiment is totest whether the measure of drops effect the consider of reaction.Word comparabilityZinc(s) + Sulphuric acid(aq) total heat(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 there mustiness be hard collisions between thezinc and the hydrogen ions (acidity ion) from the acid, The faster theharder and the more(prenominal) often the collisions happen so I predict the more particle accelerator the faster the reaction.PlanningSafety* Sulphuric acid at 2M is a corrosive su bstance but make outd to 1M it is an Irritant, so wear a Lab coat to encourage your cloths and wear safety specs to protect your eyes.* Zinc is very flammable so do not model a Bunsen burner near it.* Copper sulphate is very loathly and corrosive when it gets in your eyes so wear safety specs.* Hydrogen is explosive when mixed with oxygen and burnt so dont use a Bunsen burner near the experiment.Method======First a clamp baulk was taken and a gas cyringe was fitted so thatwhen it is connected to a conicle flask the conicle flask will touchthe bench. 1 gram of zinc was taken along with 2M sulphuric acid anddistilled sollutions. The solutions were mixed to form 1 M acid and acertain number of dfrops of gun wes added in the conicle flaskand the... ...zincand the amount of copper sulphatewere not kept constant.Did I do sufficiency readingsI think I have do enough readings as the trend of my predictionswere there but I could have done a greater range. The only problemwith t hat is I would have to dilute the acid again as the times werevery quick for 15 seconds so it would be to awkward to collect if Idid 30 drops of copper suphate it would have been to quick to record.Could your results lead to any findings outside the range of resultscover?Yes I could as my graphical record is a straight line graph so I could extend itand look at maybe 40 or 50 drops and look at what the rate is for themWhat additional germane(predicate) work could you do to extend 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.
