Mass Transfer - Engineering
Q1: 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 itsA integral heat of adsorption.
B heat of wetting.
C differential heat of adsorption.
D heat of normal condensation.
ANS:A - integral heat of adsorption. The integral heat of adsorption refers to the total amount of heat absorbed or released when a gas is adsorbed onto a solid surface to form a definite concentration of adsorbate. It represents the overall heat change associated with the adsorption process from the initial state, where the adsorbent surface is free of adsorbate (often referred to as the "outgassed" state), to the final state with a specific concentration of adsorbate molecules attached to the surface. Here's how the integral heat of adsorption is typically understood and measured:
