Reaction Rate Consentration

Reactant engrossment and Rate of Reaction Aim: See scallywag 82 Exploring chemistry Stage 2 Equipment: See rogue 82 Exploring chemical science Stage 2 surgical procedure: See page 82 Exploring Chemistry Stage 2 Discussion: Study of rate of reaction betwixt atomic number 11 Thiosulfate and HCl, the rate is slower when diluted because the water particles tie the atomic number 11 thiosulfate particles to become more dispersed and so in that delight in are less successful collisions at their activation muscularity significance it takes long-term for the sec particles to be produced and thus it takes longer for the source to turn cloudy. Safety: Hydrochloric acid sulphur dioxide (produced in this reaction if asthmatic then keep your distance) Observations: Before essay: The sodium thiosulphate was a pale solution. The hydrochloric acid was also a colourless solution. During Experiment: The sodium thiosulphate reacted with the hydrocloric acid to make a reaction mixture that conducts more cloudy as yellow-bellied sulphur is create After Experiment: The sodium thiosulphate and hydrochloric acid has reacted and organize a yellow substance (sulphur dioxide). Results: Vol of 0.25 gram jettyecule/L Na2S2O3 (mL) Vol of water system added (mL) Total Vol after adding and mixing 5 mL HCl Concentration of Na2S2O3 on mixing (mol/L) Time for crossroad to disappear (s) 1 Time (s-1) 45 0 50 0.225 22 0.045 35 10 50 0.175 27 0.037 25 20 50 0.125 34 0.029 15 30 50 0.075 49 0.020 5 40 50 0.025 328 0.00309 Reaction: sodium thiosulphate »» Sulphur + Sodium Chloride + Sulphur Dioxide + water system NA2S2O3 + 2HCL »» S + 2NaCl + SO2 + H2O (aq) + (aq) »» (s) + (aq) + (g) + (l) Calculations: (C)(V)= (C)(V) (1.25)(45) = (C)(50) C = (0.25)(45) (50) !
