What is the difference between physisorption and chemisorption?
(N/A)
| Feature | Physisorption vs. Chemisorption |
|---|---|
| $1$. Nature of forces | $Physisorption$ involves weak van der Waal's forces,whereas $Chemisorption$ involves strong chemical bonds. |
| $2$. Compound formation | No new compound is formed in $Physisorption$,while new compounds are formed in $Chemisorption$. |
| $3$. Reversibility | $Physisorption$ is generally reversible,whereas $Chemisorption$ is usually irreversible. |
| $4$. Enthalpy of adsorption | $Physisorption$ has low enthalpy $(20-40 \ kJ \ mol^{-1})$,while $Chemisorption$ has high enthalpy $(40-400 \ kJ \ mol^{-1})$. |
| $5$. Temperature dependence | $Physisorption$ is favored by low temperature,while $Chemisorption$ is favored by high temperature. |
| $6$. Molecular layer | $Physisorption$ is multi-layer,whereas $Chemisorption$ is mono-layer. |
