What are potential energy curves?
In chemical bonding: The quantum mechanics of bonding. …used to construct a molecular potential energy curve, a graph that shows how the energy of the molecule varies as bond lengths and bond angles are changed.
What is the difference between physisorption and chemisorption give two points?
Physisorption is due to the formation of van der Waals forces. Chemisorption is due to the formation of chemical bonds. It is reversible in nature. It is irreversible in nature.
What is sorption phenomenon?
Sorption can be defined as a phenomenon of fixation or capture of a gas or a vapor (sorbate) by a substance in condensed state (solid or liquid) called sorbent [124].
What type of forces are responsible for the occurrence of chemisorption?
Van der Waals’ forces are responsible for chemisorption.
What is potential energy and example?
potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth.
Is bond energy potential energy?
The bond energy is energy that must be added from the minimum of the ‘potential energy well’ to the point of zero energy, which represents the two atoms being infinitely far apart, or, practically speaking, not bonded to each other. At large distances, the energy is zero, meaning that there is no interaction.
Which of the following is an example of potential energy?
Examples of Gravitational Potential Energy A raised weight. Water that is behind a dam. A car that is parked at the top of a hill. A yoyo before it is released.
What are the differences between physisorption and chemisorption give reason why a finely divided substance is more effective as an adsorbent?
A finely divided substance has a large surface area. Both physiorption and chemisorption increase with an increase in the surface area. Hence, a finely divided substance behaves as a good absorbent.
Is sorption a physical process?
Sorption is a physical and chemical process by which one substance becomes attached to another.
