Although, nitrogen does not adsorb on a surface at room temperature, it adsorbs on the surface at 83 K. Which one of the following statements is correct ?
At 83 K, there is formation of monolayer
At 83 K nitrogen is adsorbed as atoms
At 83 K nitrogen molecules are held by chemicals bonds
At 83 K there is formation of multimolecular layers
At 83 K physical adsorption takes place effectively so multimolecular layers formed.
