Results of Rates of Reaction Experiments: Throughout the experiments, I used 2 molar hydrochloric acid and 1gram of medium sized marble chips. This was to keep the tests fair. I varied the concentration of he hydrochloric acid by combining different amounts of water with different amounts of hydrochloric acid to decrease the molarity but keep the same amount of liquid in the equation. 10ml acid with 0ml water Time 1st result 2nd result 3rd result 20 0 0 0 40 1 2 4 60 8 4 9 80 11 6 12 100 14 9 15 120 16 12 18 140 18 15 19 160 20 15 21 180 22 18 24 200 25 18 24 220 28 21 24 240 28 22 260 28 22 280 25 300 25 320 25 9ml acid with 1ml water Time 1st result 2nd result 3rd result 20 8 13 12 40 16 22 17 60 22 29 22 80 24 38 27 100 28 44 31 120 35 50 35 140 39 55 40 160 40 60 43 180 50 70 46 200 62 73 50 220 73 76 52 240 77 78 53 260 83 82 57 280 87 83 60 300 90 85 62 320 93 87 64 340 95 88 66 360 98 89 68 380 100 90 70 400 100 91 72 420 100 93 74 440 93 75 460 93 77 480 78 500 79 520 83 540 83 560 83 8ml acid with 2ml water Time 1st result 2nd result 3rd result 20 0 0 0 40 3 3 5 60 5 5 9 80 8 8 10 100 10 9 12 120 13 12 14 140 16 12 17 160 17 16 19 180 19 16 20 200 19 19 22 220 22 19 22 240 22 22 22 260 22 22 280 22 7ml acid with 3ml water Time 1st result 2nd result 3rd result 20 3 4 5 40 10 7 10 60 17 10 13 80 20 12 17 100 23 14 18 120 25 27 19 140 26 28 21 160 29 30 24 180 29 30 24 200 29 30 24 5ml acid with 5ml water Time 1st result 2nd result 3rd result 20 0 0 0 40 0 0 1 60 2 1 3 80 3 1 4 100 4 2 4 120 5 3 5 140 5 4 6 160 6 5 7 180 6 5 7 200 6 5 7 3ml acid with 7ml water Time 1st result 2nd result 3rd result 20 4 2 No result 40 6 4 60 9 6 80 11 7 100 14 8 120 15 10 140 18 11 160 20 12 180 21 13 200 22 14 220 24 15 240 25 16 260 27 17 280 29 17 300 30 17 320 30 340 30 Averages of each concentration Time 100% 90% 80% 70% 50% 30% 20 0 11 0 4 0 3 40 2.3 18.3 3.6 9 0.3 5 60 7 24.3 6.3 13.3 2 7.5 80 9.6 29.6 8.6 16.3 2.6 9 100 12.6 34.3 10.3 18.3 3.3 11 120 15.3 40 13 23.6 4.3 12.5 140 17.3 44.6 15 25 5 14.5 160 18 47.6 16.6 27.6 6 16 180 21.3 57.3 18 27.6 6 17 200 22.3 61.6 19.3 27.6 6 18 220 24.3 67 21 19.5 240 25 69.3 22 20.5 260 25 74 22 22 280 25 76.6 22 23 300 25 79 23.5 320 25 81.3 30 340 83 30 360 85 380 86.6 400 87.6 420 89 440 84 460 85 480 78 500 79 520 83 540 83 560 83 Conclusion: From analysis of the results I have recorded, I have come to the conclusion that the rate of reaction gets slower when the concentration of acid is weakened. This is proven by the graphs showing my data. This proves my prediction about...
