Q. Read the given paragraph and write answers of the following questions.
When any solid substance is kept in contact with liquid or gas, then liquid or gas are more adsorbed on the surface of solid rather than bulk. The process is known as adsorption. It is different from absorption. Many gaseous reaction occurs in the presence of solid catalyst. Catalyst is a chemical substance which change the rate of reaction without undergoing itself change. This phenomenon is known as catalysis.
