- For N2 adsorbed on activated carbon at –77 °C, the following values of adsorbed gas (per gram of adsorbent) were obtained at different pressures: P/atm 3.5 10.0 16.7 25.7 33.5 39.2 v/(cm³/g) 101 136 153 162 165 166 - Estimate the volume value of the monolayer. - Calculate the coating fraction (θ) at a pressure of 10 atm. ANSWER: 0.82 - What would happen (increase / decrease) with the coating fraction at 10 atm if the temperature increased? - What would happen to the volume of the monolayer if the temperature increased? - Using the Langmuir isotherm, estimate the value of the adsorption equilibrium constant. Tip: use the overlay fraction at 10 atm (already calculated in item b) and calculate the value of K. ANSWER: 0.45When plotted according to the linear form of the BET equation, data for the adsorption of N2 on Graphon at 77 K give an intercept of 0.005 and a slope of 1.5 (both in cm3 STP per gram). Calculate Asp assuming a molecular area of 16 (angstrom)2 for N2. Calculate also the heat of adsorption for the first layer (the heat of condensation for N2 is 1.3 kcal/mol). Would your answer for Vm be much different if the intercept were taken to be zero (and the slope the same)? Comment briefly on the practical significance of your calculation.Define the nuclear reaction cross section and derive the expression for the surviving projectile paritcles after travelling through a slab of thickness x and area A.
- The volume of O2(g) adsorbed on a surface of 1 g of a silica sample at 5°C is V1=1.4 cm3 at P1=95.1 torr and V2=10.6 cm3 at P2=760 torr. Identify the maximum volume of oxygen, Vm, that can be adsorbed. Consider the Langmuir isotherm modelAccording to the nature or physical mechanism of separation, the separation process can be categorized into three main types. Write down in details what are the three main types.A certain solid sample adsorbs 0.44 mg of CO when the pressure of the gas is 26.0 kPa and the temperature is 300 K. The mass of gas adsorbed when the pressure is 3.0 kPa and the temperature is 300 K is 0.19 mg. The Langmuir isotherm is known to describe the adsorption. Estimate the fractional coverage of the surface at the two pressures.
