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

The Effect of Catalyst an the Rate Of ReactionChemistry Coursework Does The estimate of Drops of Catalyst Effect The Rate Of ReactionCandidate Name Ben DoddsCandidate Number 7158School Oundle SchoolCompletion DateIntroductionWe are study the reaction between zinc and sulfuric acid, thereaction is catalysed by copper sulphate and this experiment is totest whether the amount of drops effect the rate of reaction.Word comparisonZinc(s) + Sulphuric acid(aq) henry(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 must be hard collisions between 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.PlanningSafety* Sulphuric acid at 2M is a corrosive substance barely diluted to 1M it is an Irritant, so wear a Lab coat to protect your cloths and wear safety specs to protect your eyes.* Zinc is genuinely flammable so do non put a Bunsen burner near it.* Copper sulphate is very nasty 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 stand 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 catalyst wes added in the conicle flaskand the... ...zincand the amount of copper sulphatewere not kept constant.Did I do enough readingsI think I have done enough readings as the trend of my predictionswere there just now I could have done a greater be adrift. The only problemwith that 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 resultscovered?Yes I could as my graph 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 relevant 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.
