1) What are the difference between physisorption and chemisorption ? Physisorption Forms due to vander waal’s forces lacks specificity Reversible Low enthalpy of adsorption Multilayer adsorption Chemisorption Forms due to formation of chemical bond Highly specific in nature IrReversible High enthalpy of adsorption Mono layer adsorption 2) Mention three applications of adsorption Ans : Production of high vaccum Control humidity Chromatographic analysis Gas mask Froth flotation process 3) What is heterogeneous catalysis? give an example Ans : the catalysis in which the reactants and catalyst are in different phase is called heterogeneous catalysis. 2SO 2 + O 2 2SO 3(g) 4) Mention two characteristics of enzyme catalysis. Ans : - most highly efficient - highly specific in nature 5) Name the colloidal system in which a liquid is dispersed in the solid dispersion medium Ans : Gel 6) Difference between lyophillic and l...
