The change in enthalpy per unit weight of adsorbed gas when adsorbed on gas free or "outgassed" adsorbent to from a definite concentration of adsorbate is called its_____________________?
Correct answer: A. Integral heat of adsorption
- A. Integral heat of adsorption
- B. Heat of wetting
- C. Differential heat of adsorption
- D. Heat of normal condensation
Explanation
The integral heat of adsorption is the enthalpy change per unit mass of adsorbate for loading an initially outgassed adsorbent from zero to a specified concentration. Differential heat of adsorption instead refers to the heat for an infinitesimal change at a particular loading.
