1 L of 0.6 M acetic acid is shaken with 2 g activated carbon. Activated carbon adsorbs some acetic acid on its surface only. This process is called adsorption. The final concentration of the solution after adsorption is 0.5 M. What is the amount of acetic acid adsorbed per gram of carbon.

In case of chemical adsorption,

All adsorptions occur with release in energy and are found to be exothermic in nature. In an adsorption process, the enthalpy change for adsorption of one_____ of adsorbate on an adsorbent surface is called enthaply or heat of adsorption for the particular adsorption.

In physical adsorption, the molecules of adsorbate are held by chemical forces.

Amongst the following statements regarding adsorption, those that are valid are : (a) DeltaH becomes less negative as adsorption proceeds. (b) On a given adsorbent, ammonia is adsorbed more than nitrogen gas. (c) On adsorption, the residual force acting along the surface of the adsorbent increases. (d) With increase in temperature, the equilibrium concentration of adsorbate increases.

Increase in concentration of adsorbate at the surface of a substance as compared to bulk is called

If x/m is the mass of adsorbate adsorbed per unit mass of adsorbent, P is the pressure of the adsorbate gas ,a and b are constant ,which of the following represent "Langmuir adsorption isotherm"?

Which statement is correct when adsorption of gas take place on metal surface? (a) delta H becomes less negative with pregress of reaction. (b) with progress of reaction the strength of residual forces increases. (c) NH_3 is adsorbed more than N_2 . (d) Equilibrium concentration of adsorbate increases with increase in temperature.
