What is a negative - positive?
Negative * positive = negative Positive * positive = positive Negative * negative = positive

When multiplying numbers what do you do with the positive and negative signs?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
What is a positive plus a positive?
a positive
What is the reaction of positive and positive?
A positive
Does chemical adsorption have a high adsorption enthalpy?
no
Why physical adsorption is reversible process?
Physical adsorption is reversible because the forces involved are weak van der Waals forces, such as London dispersion forces or dipole-dipole interactions. These forces can be easily disrupted by changes in temperature or pressure, allowing the adsorbate to be released from the adsorbent surface. This reversibility distinguishes physical adsorption from chemical adsorption, which involves stronger, more covalent bonds.
Does physical adsorption have a low adsorption enthalpy?
Yes, physical adsorption typically has a low adsorption enthalpy due to weak van der Waals forces between the adsorbate and adsorbent. These interactions are reversible and non-specific, leading to lower enthalpies compared to chemical adsorption.

What is adsorption site?
An adsorption site is a location on a surface where molecules or particles can adhere or bind due to attractive forces. It is where adsorption occurs, where a substance accumulates on the surface of another material. Adsorption sites are important in processes like catalysis, gas separation, and water treatment.
Is adsorption spontaneous?
Yes, adsorption is typically a spontaneous process because it involves the attraction of molecules to a surface due to the energetically favorable interactions between them. This can result in a decrease in free energy and an increase in the stability of the system.
How does adsorption work in reality?
In reality, adsorption is a process where molecules in a gas or liquid adhere to the surface of a solid. This occurs due to the attractive forces between the molecules and the solid surface. Adsorption is used in various applications such as purifying gases, wastewater treatment, and catalysts.

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 other word for Adsorption?
Migration or segregation.
