The adsorption of a gas on solid material follows the Langmuir Isotherm with K= 0.75 KPa at 298 K. Calculate the pressure at which the fractional coverage is 0.5.
Solution
=(KP)/(1+KP)
fraction is the surface covered by adsorbed molecule
0.5=(0.75P)/(1+0.75P)
0.5(1+0.75P)=0.75P
0.5+0.375P=0.75P
0.375P=0.5
P=1.33 KPa
