    \r\n \t
  1. Ideal Gas Law\r\n
      \r\n \t
    1. A sample of volatile liquid with the formula C2H6O2 was measured in a steel container.It contains a mass of 4.85 grams.<\/li>\r\n \t
    2. Convert the grams of the gas to mols. Record your data.<\/li>\r\n \t
    3. The container is recorded to have precisely 500.0 mL when filled.<\/li>\r\n \t
    4. Convert this to L and record your data.<\/li>\r\n \t
    5. The sample of liquid is closed into the container and heated.<\/li>\r\n \t
    6. A series of temperature measurements are taken and included in your data section.Convert these to K.<\/li>\r\n \t
    7. Use the Ideal Gas Law to find the pressure in the container at each set of conditions.<\/li>\r\n \t
    8. Graph Pressure vs Temperature (in Kelvin) manually in the space provided.<\/li>\r\n \t
    9. Attach a graph made in excel in the space provided. Include the trendline and theequation of the line on the graph.<\/li>\r\n<\/ol>\r\n<\/li>\r\n \t
    10. Kinetics\r\n
        \r\n \t
      1. The decomposition of a colored compound was measured over time by taking samples atdistinct intervals and monitoring the absorbance. A set of standards confirmed that theabsorbance was related to concentration by A = 1.25(M)+ 0.114.<\/li>\r\n \t
      2. Convert the given Absorbance data to molarity using the equation above.<\/li>\r\n \t
      3. Since decomposition reactions are usually not linear relationships it is sometimes useful toconsider the LN of the molarity rather than molarity itself. Convert the molarity toLN(molarity) in the space provided.<\/li>\r\n \t
      4. Manually create a graph of Molarity vs. Time in the space provided. Use a ruler to draw aline of best fit through the data points.<\/li>\r\n \t
      5. Create a graph of Ln(M) vs Time in Excel and attach it in the space provided. Include atrendline with the equation of the line displayed on the chart.<\/li>\r\n \t
      6. From this trendline calculate the LN(M) that would be present at 275 seconds. Use thisnumber to determine the molarity present at that time.<\/li>\r\n<\/ol>\r\n<\/li>\r\n \t
      7. Clausius-Clapeyron<\/li>\r\n<\/ol>\r\n1. The temperature and Pvap for dichloromethane are given. Convert the units to 1\/T and\r\n\r\n<\/div>\r\n<\/div>\r\n
        \r\n
        \r\n\r\nLN(Pvap). Record your data\r\n
          \r\n \t
        1. Manually graph the relationship between Ln(P) and 1\/T.<\/li>\r\n \t
        2. Create a graph of LN(P) vs 1\/T in Excel and include it in the space provided.<\/li>\r\n \t
        3. Use the trendline to determine the Hvap of dichloromethane.<\/li>\r\n<\/ol>\r\n<\/div>\r\n

            Experimental Procedure<\/p>\n

              \n
            1. Ideal Gas Law\n
                \n
              1. A sample of volatile liquid with the formula C2H6O2 was measured in a steel container.It contains a mass of 4.85 grams.<\/li>\n
              2. Convert the grams of the gas to mols. Record your data.<\/li>\n
              3. The container is recorded to have precisely 500.0 mL when filled.<\/li>\n
              4. Convert this to L and record your data.<\/li>\n
              5. The sample of liquid is closed into the container and heated.<\/li>\n
              6. A series of temperature measurements are taken and included in your data section.Convert these to K.<\/li>\n
              7. Use the Ideal Gas Law to find the pressure in the container at each set of conditions.<\/li>\n
              8. Graph Pressure vs Temperature (in Kelvin) manually in the space provided.<\/li>\n
              9. Attach a graph made in excel in the space provided. Include the trendline and theequation of the line on the graph.<\/li>\n<\/ol>\n<\/li>\n
              10. Kinetics\n
                  \n
                1. The decomposition of a colored compound was measured over time by taking samples atdistinct intervals and monitoring the absorbance. A set of standards confirmed that theabsorbance was related to concentration by A = 1.25(M)+ 0.114.<\/li>\n
                2. Convert the given Absorbance data to molarity using the equation above.<\/li>\n
                3. Since decomposition reactions are usually not linear relationships it is sometimes useful toconsider the LN of the molarity rather than molarity itself. Convert the molarity toLN(molarity) in the space provided.<\/li>\n
                4. Manually create a graph of Molarity vs. Time in the space provided. Use a ruler to draw aline of best fit through the data points.<\/li>\n
                5. Create a graph of Ln(M) vs Time in Excel and attach it in the space provided. Include atrendline with the equation of the line displayed on the chart.<\/li>\n
                6. From this trendline calculate the LN(M) that would be present at 275 seconds. Use thisnumber to determine the molarity present at that time.<\/li>\n<\/ol>\n<\/li>\n
                7. Clausius-Clapeyron<\/li>\n<\/ol>\n

                  1. The temperature and Pvap for dichloromethane are given. Convert the units to 1\/T and<\/p>\n<\/div>\n<\/div>\n

                  \n
                  \n

                  LN(Pvap). Record your data<\/p>\n

                    \n
                  1. Manually graph the relationship between Ln(P) and 1\/T.<\/li>\n
                  2. Create a graph of LN(P) vs 1\/T in Excel and include it in the space provided.<\/li>\n
                  3. Use the trendline to determine the Hvap of dichloromethane.<\/li>\n<\/ol>\n<\/div>\n
