Question 1.
What does the variable 'x' represent in the Freundlich equation?
Show hintHide hint
Think about what is being adsorbed.
Question 2.
What does 'P' stand for in the context of the Freundlich Isotherm?
Show hintHide hint
Consider the forces acting on gas molecules.
3Question 3.
What does the Freundlich Isotherm describe?
- a) Melting point of solids
- b) Relationship between pressure and adsorption
- c) Rate of chemical reactions
- d) Temperature dependency of gases
Show hintHide hint
Think about what the term isotherm relates to.
4Question 4.
True or False: The Freundlich Isotherm only applies to single layer adsorption.
- True
- False
Show hintHide hint
Consider the nature of the adsorption process.
Question 5.
Given the Freundlich isotherm equation x/m = 3P^(2/3), determine the mass of adsorbate if the pressure is halved and the mass of adsorbent remains constant at 10g.
Show hintHide hint
Start by substituting P/2 in the equation.
Question 6.
If the experimental values determine k = 2 and n = 0.5, what happens to adsorption if pressure increases?
Show hintHide hint
What could a fractional 'n' imply about the rate of increase?
