Catalysts speed up reactions by providing an alternative pathway with lower activation energy. While they influence reaction rates, they do not directly change the specific rate constant, which is a characteristic of the reaction itself.

What kind of kinetics is characteristic of elimination bimolecular reactions?
Bimolecular elimination reactions involve the collision of two molecules, resulting in a rate that depends on the concentration of both reactants, hence following second-order kinetics.

What substance is used to prepare ammonia when heated with ammonium chloride?
Ammonia is prepared by heating ammonium chloride with aqueous sodium hydroxide (caustic soda solution), releasing NH3 gas. This reaction is a common method for producing ammonia in the laboratory.

What term describes a compound's ability to form multiple distinct crystal structures?
Polymorphism refers to the ability of a compound to exist in multiple crystalline forms, differing in crystal structure but not in chemical composition. This occurs due to variations in the arrangement of molecules within the crystal lattice.
