On increasing which of the following factors, decreases the extent of physisorption? Surface area of the adsorbent Critical temp
Citrus2011 [14]

Answer: On increasing temperature at which adsorption is carried out decreases the extent of physisorption.

Explanation:

An adsorption where molecules of the adsorbate are placed or held on the surface of adsorbent by Vander waals forces is called physisorption.

There is basically physical bonding between the molecules of gas to the surface of a solid or liquid.

Physisorption is reversible in nature and occurs at low temperatures.

It is not specific in nature which means that all gases are adsorbed on the surface of every solid substance to some extent.

Thus, we can conclude that on increasing temperature at which adsorption is carried out decreases the extent of physisorption.

You have forgotten the ideal gas constant. Describe an experiment, similar to this one, that would allow you to determine the va
Gelneren [198K]

Information would you need to know about the H₂O₂ solution is through stoichiometry experiment

The ideal gas constant R can be found experimentally by determining the number of moles of gas that occupies a particular measured volume at a known pressure and temprature and the H₂O₂ is a chemical compound used un various chemical reactions and is slightly viscous than water and the experiment by decomposition of hydrogen peroxide and using the ideal gas law rearrangement equation we can calculate the value of r and we will need the information such as concentration, volume and moles of  H₂O₂ to determine its stoichiometry

Know more about ideal gas constant
