Given the limitations of the Langmuir model, many other empirical adsorption isotherms have been proposed to better reproduce observed adsorption behavior. One of these empirical isotherms is the Temkin isotherm: V _adsorbed = r ln (sP), where V is the volume of gas adsorbed, P is pressure, and r and s are empirical constants.

a. Given the Temkin isotherm provided, what type of plot is expected to give a straight line?

b. Use your answer from part (a) to determine r and s for the data presented in Problem P36.24.
