A certain solid sample adsorbs 0.63 mg of CO when the pressure of the gas is 36.0 kPa and the temperature is 300 K. The mass of gas adsorbed when the pressure is 4.0 kPa and the temperature is 300 K is 0.21 mg. The Langmuir isotherm is known to describe the adsorption. Estimate the fractional coverage of the surface at the two pressures.

Step 1
Step 1: Understand the Langmuir isotherm equation, which is given by: \[ \theta = \frac{bP}{1 + bP} \] where \( \theta \) is the fractional coverage, \( b \) is the Langmuir constant, and \( P \) is the pressure. Show more…

The pressures of nitrogen required for adsorption of $1.0 \mathrm{cm}^{3} \mathrm{g}^{-1}\left(25^{\circ} \mathrm{C}, 1.013 \mathrm{bar}\right)$ of gas on graphitized carbon black are 24 Pa at $77.5 \mathrm{K}$ and 290 Pa at $90.1 \mathrm{K}$. Calculate the enthalpy of adsorption at this fraction of surface coverage.
