Question

PLease show all work. Thank you.

1.) The adsorption of CO on activated carbon was followed experimentally at 0°C. At the given e es, the following que pressures, the following quantities of adsorbed gas were measured a. Determine whether the measurements conform to the Langmuir isotherm b. Calculate the adsorption-desorption equilibrium constant KA c. Calculate the volume corresponding to a full monolayer coverage. Co V [cm3]10.3 19.3 27.3 34.1 4045.5

Answer 1

P	V	P/V
133	10.3	12.91262
267	19.3	13.8342
400	27.3	14.65201
533	34.1	15.6305
667	40	16.675
800	45.5	17.58242

P/V= (P/Vm) + (1/KVm)

slope	1/ Vm    =	0.007
	Vm      =	142.8571

intercept	1/KVm    =	11.93
	K         =	0.000587

a)	Follows Langmuir isotherm
b)	KA	0.000587
c)	Vm	1704.286
