### Cоnsider the fоllоwing tаble thаt lists the orthobаric densities of the liquid and gaseous phases of trimethysilane in equilibrium along the liquid–vapor coexistence curve as a function of temperature: Liquid Gas T (K) ρ (g/cm3) T (K) ρ (g/cm3) 353.64 0.56470 353.55 0.01558 362.59 0.55200 360.30 0.01819 372.71 0.53670 367.21 0.02135 383.15 0.51982 367.32 0.02173 392.20 0.50395 372.18 0.02429 397.43 0.49415 376.94 0.02712 407.96 0.47268 387.19 0.03410 418.68 0.44718 389.70 0.03600 423.46 0.43276 397.35 0.04292 424.05 0.43241 405.44 0.05120 428.46 0.41881 407.74 0.05408 433.91 0.39943 413.30 0.06118 439.60 0.37373 418.56 0.06922 445.29 0.33434 418.73 0.06932 447.75 0.29942 424.37 0.07947 447.84 0.29732 429.94 0.09185 433.08 0.10000 434.70 0.10485 441.72 0.13289 443.55 0.14343 444.65 0.15128 445.36 0.15728 446.02 0.16344 446.63 0.17025 447.21 0.17830 447.36 0.18085 447.84 0.18954 448.14 0.19769 448.33 0.20482 Open the Microsoft Excel spreadsheet that is attached below and use it as a template to answer the following questions:CHM 4410 Exam 3 Question 4 Template.xlsx (a) Plot the orthobaric densities of the liquid and gaseous phases of trimethylsilane as a function of temperature and fit the entire density data for both phases, individually, to a generic nth-degree polynomial (n = 5 or 6) using the built-in polynomial fitting function in Microsoft Excel. Include the equation (with ≥ 15 decimal places for the coefficients) and R2 value for the best-fit line for both plots.(b) Determine precise values for the critical temperature (in K), critical density (in g/cm3), and critical molar volume (in L/mol) of trimethylsilane (M = 74.20 g/mol). Hint: Use the Newton–Raphson method.Attach the raw Microsoft Excel spreadsheet containing your attempt of this question in XLS or XLSX format below. There should only be one graph for this question.
