1.	Explain how the phenomenon of adsorption finds application in each of the following processes :Production of vacuumHeterogeneous catalysisFroth floatation process
Answer» Production of vacuum : Remaining gas present in a vessel after creation of vacuum can be absorbed on the surface of charcoal, so that more efficient vacuum can be produced. Heterogeneous catalysis : In such catalysis, reactants get adsorbed on the surface of catalyst so that collision among the reactant molecules increases as well as the enthalpy of adsorption is utilised in providing the activation energy to reactants to undergo the reaction. Froth floatation process : Ore particles get adsorbed on the surface of pine oil, hence they can be separated as froth by blowing air through it.
