The concentration (in mg/L) of chloramphenicol at three different temperatures over time is provided below. Time (day) -18°C 25°C 40°C 25 28 23 7 27 20 20 30 20 21 20 180 23 25 19 (a) Using the data in the tables below assess and explain if the reaction time (after 1 hour of the start of the reaction) was an important factor affecting the yield of the reaction and provide the null hypothesis of the statistical test carried out. (b) The amount of chloramphenicol at -18 °C seems to vary with some values appearing to be higher than others. Explain what may be causing this variation AND suggest a methodology to identify if there was a systematic error in the measurement. ||

A typical HPLC column is 15.0 cm long and 4.6 mm in diameter. What is the internal volume of the column? What is the volume of a 5-μm diameter particle (approximate it as a hard sphere)? Because of the way spherical particles pack in a column, the volume that is external to the particles is approximately 40% of the entire column volume, meaning that 60% of the column volume is occupied by the particles. Given this, the total column volume you calculated in part (a), and the volume of a particle you calculated in part (b), calculate the number of particles packed in a 15.0 cm x 4.6 mm column
