Embibe Experts Solutions for Chapter: Surface Chemistry, Exercise 1: Exercise-1

Give two examples for heterogeneous catalysis.

Following is the variation of physical adsorption with temperature:

Finely divided catalysts have greater surface area and have greater catalytic activity than the compact solid. If a total surface area of $6291456 {\mathrm{cm}}^2$ is required for adsorption in a catalysed gaseous reaction, how many splits should be made to a cube of exactly $1 \mathrm{cm}$ in length to achieve required surface area. (Given: One split of a cube gives eight cubes of same size)?

At CMC, the surfactant molecules:

Protective sols are:

Which of the following ions is the most effective in the coagulation of an arsenious sulphide solution?

Which of the following ions is the most effective in the coagulation of ferric hydroxide solution?

Small liquid droplets dispersed in another liquid is called:
