Surface Chemistry Quiz-1

Dear Readers,

The one subject in NEET which is candidates who can easily attain good marks is Chemistry. That's the reason, often, one doesn’t pay notice and choose to compromise it. But if one wants to rank above others, the tip is to be thorough with NEET chemistry concepts. The understanding of reactions and definite basic understanding is what requires major attention in Chemistry but once done it only gets simpler from there. The main focus on the to-do list should be on getting a hang of the NCERT syllabus of NEET chemistry..

Q1. The size of colloidal particles is in between
  •  
  •  
  •  
  •  
Solution
The size of colloidal particles is in the range of 100 nm to 1nm or 

Q2.A substance which promotes the activity of a catalyst is known as :
  •  Initiator
  •  Catalyst
  •  Promoter
  •  Auto-catalyst
Solution
It is the definition of promoter or in other words lowers the energy of activation.

Q3.  Lyophobic colloids are :
  •   Reversible colloids
  •  Irreversible colloids
  •  Protective colloids
  •  Gum, proteins
Solution
Lyophobic sols are irreversible. Rest all points signify for lyophilic sols.

Q4. Which of the following types of catalysis can be explained by the adsorption theory?
  •  Homogeneous catalysis
  •  Acid-Base catalysis
  •  Heterogeneous catalysis
  •  Enzyme catalysis
Solution
Adsorption theory involves adsorption of gas on solids.

Q5.If dispersion medium is water, the colloidal system is called :
  •  Sol
  •  Aerosol
  •  Organosol
  •  Aquasol
Solution
 Sols having water as dispersion medium (D.M.) are called aquasol. If benzene is D.M., it is benzosol. If alcohol is D.M., it is alcosol.

Q6. If liquid is dispersed in solid medium, this is called
  •  Sol
  •  Emulsion
  • Liquid aerosol
  •  gel
Solution
When a liquid (dispersed phase) is dispersed in solid (dispersion medium), the colloidal solution is termed as gel.

Q7.Which is universally correct for catalyst?
  •  A catalyst remains unchanged chemically at the end of chemical reaction
  •  A catalyst takes part in a chemical reaction
  •  All kinds of catalysts undergo catalytic poisoning
  •  A catalyst physically changes at the end of reaction The Prime Minister
Solution
The physical state changes but chemically it remains same. .

Q8.The Brownian motion is due to:
  •  Temperature fluctuations within the liquid phase
  •  Attraction and repulsion between charges on the colloidal particles
  •  Impact of the molecules of the dispersion medium on the colloidal particles
  •  Convective currents
Solution
The dispersed phase particles bear continuous collisions with dispersion medium irregular motion in sol state

Q9.Bredig arc method cannot be used to prepare colloidal solution of :
  •  Pt
  •  Fe
  •  Ag
  •  Au
Solution
Bredig arc method is used to prepare the metalsols which do not react with water even at high temperature.

Q10. The activity and selectivity of zeolites as catalyst is based on :
  •  Their pore size
  •  Size of their cavities on the surface
  •  Both (a) and (b)
  • None of the above
Solution
Larger is surface area, more is efficiency of catalyst. The surface area becomes more in finely powdered state, colloidal state or if surface is rough.
