MHT CET 2024 Chemistry question

Which among the following statement is NOT true about rate constant ?

(A)It is independent of concentration.
(B)It varies with temperature.
(C)For unit concentration it is equal to rate of reaction.
(D)It is directly proportional to the product of concentrations of reacting species.Correct

Answer: (D)

Solution

The rate constant in rate = is a proportionality constant: it does not depend on concentrations (A true), it depends on temperature through the Arrhenius equation (B true), and when
