4. Adsorption Isotherm Curve: The low pressure (beginning region) of an adsorption isotherm curve can be approximated with a linear equation of the form: X₁* = K x P₁. The data in the table below provides laboratory measured values of the partial pressure of an adsorbate P¡ versus the mass fraction of adsorbate on the adsorbent X;*. Determine the value of K for the equation above using the data in the table, and also provide the r-squared value of this linear equation fit. Recommend you use the linear regression function in EXCEL to determine these answers. X* (gr adsorbate/gr PCC14 (mm Hg) adsorbent) 0 0 2 0.084 3.5 0.15 5 0.27 7 0.38 10 0.525 Value of K in equation above r-squared value from linear equation fit

The fraction recrystallized-time data for the recrystallization at 350°C of a previously deformed aluminum are tabulated here. Assuming that the kinetics of this process obey the Avrami relationship, determine the fraction recrystallized after a total time of 116.8 min. Assume y1 = 0.38 and y, = 0.73. Fraction Recrystallized Time (min) 95.2 126.6 i

Determine the supersaturation ratio, S, required to permit 0.5-mmdiameter crystals ofsucrose (MW = 342 and ρc = 1,590 kg/m3) to grow if σs,L = 0.01 J/m2. Assume the temperature is 25°C.
