Areaction occurs between reactants x and z. doubling the concentration of x while the concentration of z is constant doubles the rate. tripling the concentration of z while the concentration of x is constant does not affect the rate.

what is the rate law for this reaction?

The rate law is,  .

Solution:- Let's say the order of reaction with respect to Z and X is n and m respectively.

So, the rate law in general could be written as:

where k is the rate constant.

If we take a look at the given information then, Doubling the concentration of X while concentration of Z is constant doubles the rate. It means the reaction is first order with respect to X and hence the value of m is 1.

Tripling the concentration of Z while the concentration of X is constant does not affect the rate. Here the rate is independent on the concentration of Z. It indicates the reaction is zero order with respect to Z and so the value of n is 0.

So, the rate law will be, .

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.
