Question

A unimolecular reaction follows first order kinetics, and a bimolecular reaction follows

second order kinetics.
A) True
B) False

Answer 1

A) True.

A unimolecular reaction involves the transformation of a single molecule and follows first order kinetics. This means that the rate of the reaction is directly proportional to the concentration of the reactant, and the reaction rate constant is a first-order rate constant.

A bimolecular reaction involves the collision of two molecules and follows second order kinetics. This means that the rate of the reaction is proportional to the square of the concentration of the reactants, and the reaction rate constant is a second-order rate constant.
