Question
w na mas of limonene was recovered from the S) Compare Sield greenness, and purity of your extraction to those of at least one other extraction method such as steam distillation or solvent extraction. Provide a reference within your post- lab report to support your discussion. References should be formatted in accordance with the ACS Style Guide.

Although the system is not at equilibrium, the phase diagram and physical observations can be used to estimate the conditions in the tube. Observation of both the gas/liquid and solid Miquid interfaces indicates that locally the temperature is between the temperature at the triple point (-566 ) and the critical temperature (31.1 °C). Formation of ice on the surface of the tube further brackets the temperature to between -56.6 and 0°C. The pressure is passively regulated by the leaking from the tube and, due to the liquefaction, is assumed to be above the pressure at the triple point (5.2 bar) but below the pressure that would induce tube rupture. These observations indicate that conditions approach thosc of the triple noint 4) This lab was adapted from Mckenzie, L.C.; Thompson, J. E.; Sullivan, R.; Hutchison. J. E. Green Chem. 2004, 6, 355-358.Explanation / Answer
Firstly The experiment is unknown to me as it has not provided in the question. Secondly if experiment is done after that results should come and from the results we can discuss all the answers. Having no idea about experiment and results it is not possible to answer questions.
