The reaction a + b → c is studied similarly to our study of phenolphthalein fading kinetics. the corresponding rate law is rate = k[a]m[b]m in this particular experiment, the concentration of a is sufficiently high that the pseudo-order rate law: rate = k1[b]n can be written, where k1 = k[a]m. if the study establishes that the reaction is first order in b (n = 1) and that the pseudo rate constant k1 has the following values at varying concentrations of b, what is the order of the reaction in reactant a (what is the value of m)? k1 [b] 0.0034 0.200 m 0.0020 0.100 m 0.0010 0.050 m

m=9

step-by-step explanation:

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.
