What is the difference between physisorption and chemisorption?

In physisorption, adsorption is generally ____________.

In physical adsorption, gas molecules are bound on the solid surface by

The physical adsorption is due to ____________.

What is the role of adsorption in heterogenous catalysis?

Assertion: Detergents with low CMC are more economical to use.

Reason: Cleansing action of detergents involves the formation of micelles. These are formed when the concentration of detergents becomes equal to CMC.

In which of the following reactions heterogenous catalysis is involved?

(a) \[\ce{2SO2 (g) + O2 (g) ->[NO(g)] 2SO3 (g)}\]

(b) \[\ce{2SO2 (g) ->[Pt(s)] 2SO3 (g)}\]

(c) \[\ce{N2 (g) + 3H2 (g) ->[Fe(s)] 2NH3 (g)}\]

(d) \[\ce{CH3COOCH3 (l) + H2O (l) ->[HCI(l)] CH3COOH (aq) + CH3OH (aq)}\]
