Illustrate graphically the effect of temperature on adsorption at constant pressure both for physisorption and chemisorption.besides frundlich's and Langmuir's adsorption isotherms what other such isotherms are there?discuss briefly on them.

Expert Answer
An increase in temperature decreases physical adsorption whereas, chemisorption first increases and then decreases.
There are three main adsorption isotherms:
- Frundlich's adsorption isotherm
- Langmuir's adsorption isotherm
- BET adsorption Isotherm
Other than above isotherms there are some models Polanyi Potential Theory and Dubinin-Radushkevich Equation which are for microporous adsorption.
