Figure out which of the following is not an application of adsorption?

Which of the following statements regarding a catalyst is true?

In a reversible reaction, the role of a catalyst is to

Which of the following type of catalysis can be explained by the adsorption theory?

A biological catalyst is essentially

Colloidal solution $\mathrm{A}\underset{\mathrm{process}}{\overset{\mathrm{Physical}}{\to }}\mathrm{B}+\mathrm{C}$. Osmotic pressure of $\mathrm{B}$ and $\mathrm{C}$ are found to be higher and lower than $\mathrm{A}$, respectively. Then

A freshly prepared $\mathrm{Fe}(\mathrm{OH}{)}_3$ precipitate is peptised by adding ${\mathrm{FeCl}}_3$ solution. The charge on the colloidal particle is due to preferential absorption of _______.
