Adsorption of gases on solid surface is exothermic because:

If the adsorption is due to the weak van der waals forces between adsorbent and adsorbate, it is termed as 

The correct option among the following is:

Identify the Incorrect statement among the following regarding Brownian movement.

Adsorption of a gas follows Freundlich adsorption isotherm. x is the mass of the gas adsorbed on mass m of the adsorbent. The plot of \(\log \frac{{\rm{x}}}{{\rm{m}}}\) versus log p is shown in the given graph. \(\frac{{\rm{x}}}{{\rm{m}}}\) is proportional to:

The increasing order of adsorption power of adsorbents is given by

Which of the following is not an example of heterogeneous catalytic reaction?

The amount of gas adsorbed on a solid surface  

Match the catalysts (Column I) with products (Column II).

In Freundlich isotherm, a linear relationship is obtained in the plot of

(θ = surface coverage and p = partial pressure of the gas)
