In a certain area of ​​the apparatus, where the pressure is 1 atm and the temperature is 200 ° C, the analysis of the gas is 33.33% NH 3 (A), 16.67% N 2 (B), and 50% H 2 (C) by volume. The conditions are such that the
ammonia diffuses from the gas stream to the catalyst surface; also the
products of the reaction diffuse in the opposite direction, as if there were molecular diffusion to
through a 1 mm thick gaseous film under a laminar regime.
Report the following:
a) N A, z:

the answer is the first option

explanation:

just googled it m8. not that hard

lol

explanation:

2b2t

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
