Leen Alyaseen Summary of Results:In this experiment, we observed the kinetics of an SN1 solvolysis reaction, and how changing the solvent polarity affected the rate of reaction. Each solution was placed on a magnetic stirrer, and we recorded the volume of NaOH that we added to the solution. The time and volume were both recorded each time the solution turned green, meaning that enough HCl had formed to neutralize the NaOH.For the first Kinetic Run #1Buret Reading Time(sec) (t=tn-t0)(sec) (V∞-Vt) (V∞-V0)/ (V∞-Vt) ln (V∞-V0)/ (V∞-Vt)V0: 14.80 mL 0.000 0.0 17.25 mL 1.000 mL 0.000 mLV1: 15.80 mL 93.00 93.00 16.25 mL 1.061mL 0.05800 mLV2: 17.80 mL 392.0 392.0 14.25 mL 1.210 mL 0.1900 mLV3: 19.80 mL 682.0 682.0 12.25 mL 1.400 mL 0.3300 mLV4: 21.90 mL 974.0 974.0 10.15 mL 1.700 mL 0.5300 mLV5: 23.90 mL 1218 1218 8.960 mL 1.920 mL 0.650 mLV∞: 32.05 mLFor the second Kinetic Run #2, Buret Reading Time(sec) (t=tn-t0)(sec) (V∞-Vt) (V∞-V0)/ (V∞-Vt) ln (V∞-V0)/ (V∞-Vt)V0: 14.80 mL 0.000 0.000 17.45 mL 1.00 mL 0.000 mLV1: 15.90 mL 0.4500 0.4500 16.35 mL 1.060 mL 0.05820 mLV2: 17.80 mL 132.6 132.6 14.45 mL 1.210 mL 0.1910 mLV3: 19.90 mL 240.6 240.6 12.35 mL 1.410 mL 0.3430 mLV4: 22.00 mL 316.2 316.2 10.25 mL 1.710 mL 0.5360 mLV5: 23.90 mL 394.2 394.2 8.350 mL 2.080 mL 0.7320 mLV∞: 32.25 mLErrors:One common error was not recording the time at the exact second that the solution turned green. A couple of the times, we stopped the timer a little bit after it turned green, so this could have altered our results. Students setting their magnetic stirrer at a higher rate could also increase the rate of reaction. Also, if the timer was not started right when the HCl was added, it would alter all of the results.Conclusion:The results reveal that Kinetic Run #2 had a faster rate than Kinetic Run #1. On the graphs below, we plotted the values of ln [(V∞-V0)/ (V∞-Vt)] vs time (in seconds). It is shown that the slope, or rate constant, of #1 was 0.00053, and the slope of #2 was 0.0018. Since #2 had a higher rate constant, it had a higher reaction rate. This makes sense, since #2 contained 60% water,making it a more polar solvent. The more polar the solvent, the faster the dissociation of the alkylchloride will happen, which is the rate determining step in an SN1 reaction. This confirms the proposed mechanism for the reaction, because the nucleophile must be the solvent;
