The reaction between zinc (zn) and hydrogen chloride (hcl) produces zinc chloride (zncl), hydrogen (h2) gas, and heat. if more heat is removed from the reaction, how does the rate of reaction change to counter the action? zn + 2hcl ⇌ zncl2 + h2 + heat the rate of the and produces more blank 1. reverse reaction decreases forward reaction decreases forward reaction increases blank 2. hydrogen chloride zinc zinc chloride

 If more   heat  is removed from the reaction the rate of reaction change as below to counter the action

The rate of the  forward reaction increase and produces more   zinc chloride

     explanation

what are the statements

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.
