Is adsorption a chemical process in which one substance is taken up by another?
Yes, adsorption is a process in which one substance (the adsorbate) is attracted and binds to the surface of another material (the adsorbent) through physical or chemical interactions. This results in a concentration of the adsorbate at the surface of the adsorbent.
What is the difference between adsorption and condensation?
Adsorption is when a substance gets absorbed INTOthe surface of another substance.Condensation is when a substance collects ON the surface of another substance.
What should be result of adsorption acetic acid on charcoal?
The acetic acid molecules will be attracted to the surface of the charcoal due to adsorption, leading to their accumulation on the charcoal's surface. This process can be used to remove acetic acid from a solution through physical adsorption without undergoing a chemical reaction.
How do you calculate the enthalpy change of a reaction?
To calculate the enthalpy change of a reaction, subtract the total enthalpy of the reactants from the total enthalpy of the products. This difference represents the enthalpy change of the reaction.
What do the symbols mean Delta Hr Hf Hc Hn Ha in chemistry btw i know theyre enthalpy changes?
delta Hr is the enthalphy change of a reaction delta Hf is the enthalpy of formation where one mole of a substance is formed ( generally in its naturally occurring physical state) delta Hc is the enthalpy of combustion where one mole of a substance in its standard state undergoes combustion delta Hn is the enthalpy of neutralization where one mole of H+ reacts with OH- to form one mole of H2O delta Ha is the enthalpy of atomization where a molecule splits to form its neutral atomic components
Does chemical adsorption have a high adsorption enthalpy?
no
Why physical adsorption is reversible process?
adsorption is processs of accumulation of liquid/gases on solid surface. reversible adsorption is seen in physical adsorption where increase in pressure increases the adsorption and decrease in pressure decrease adsorption of molecules to surface that is desorption takes place
Is kaolin a physical or a chemical process?
Adsorption on kaolinite is physical
Is adsorption a chemical process in which one substance is taken up by another?
Yes, adsorption is a process in which one substance (the adsorbate) is attracted and binds to the surface of another material (the adsorbent) through physical or chemical interactions. This results in a concentration of the adsorbate at the surface of the adsorbent.
What is meant by isosteric heat?
Isosteric heat refers to specific adsorption heat. It is the partial derivative of the enthalpy change of the system with regards to temperature, pressure and surface area.
What is Freundlich adsorption isotherm and Langmuir isotherm?
At a given temperature, the extent of adsorption will increase with the increase of pressure of the gas. The extent of adsorption is measured as x/m, where mi= is the mass of adsorbent and x that of adsorbate. At low pressure, x/m varies linearly with p. As per Freundlich adsorption equation Taking log both sides of the equation, we get, At low pressure, x/m=kP At high pressure, x/m=kPo This is called Freundlich adsorption isotherm at a constant temperature. Freundlich isotherm fails at high pressure and is only for physical adsorption. Langmuir isotherm is represented as x/m=ap/(1+bp) (a and b are constants) At very high pressure,(bp>>1) x/m=a/b At very low pressure,(bp<<1) x/m=ap
Is enthalpy of fusion a chemical property?
Enthalpy of fusion is a physical property, not a chemical property. It represents the amount of heat energy required to change a substance from a solid to a liquid state at its melting point.
What has the author James Procter Murray written?
James Procter Murray has written: 'Physical chemistry of virus adsorption and degradation on inorganic surfaces' -- subject(s): Purification, Sewage, Poliovirus, Adsorption
What is the physical significance of enthalpy?
it is the total energy required to create any system by displacing its volume and pressure.

Adsorption is when a substance gets absorbed INTOthe surface of another substance.Condensation is when a substance collects ON the surface of another substance.
