At equilibrium, what is the rate of production of reactants compared with the rate of the production of products?
a.) much higher
b.) higher
c.) the same
d.) lower

Option (C) is the correct answer.

Explanation:

A reaction in which the concentration of reactants and concentration of products are constant is known as an equilibrium reaction.

Also, in a equilibrium reaction the rate of forward reaction is equal to the rate of backward reaction. This means that the reaction is reversible in nature.

Thus, we can conclude that at equilibrium, the rate of production of reactants compared with the rate of the production of products is the same.

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.
