The rate constant of a reaction depends upon

A

temperature

B

initial concentration of the reactants

C

time of reaction

D

extent of reaction

Text Solution

Verified by Experts

The correct Answer is:
a
It is a constant of a particular reaction at a given temperature. It does not depend upon initial concentration of the reactants, time of reaction and extent of reaction.

    Rate of reaction depends upon

    The rate constant of a reaction varies :

    In acidic medium the rate of reaction between [BrO_(3)^(-)] and [Br^(-)] ions given by the expression - (d[BrO_(3)^(-)])/(dt) = k [BrO_(3)^(-)][Br^(-)][H^(+)]^(2) It means (i) rate of constant of the reaction depends upon the concentration of H^(+) ions (ii) rate of reaction is independent of the concentration of acid added (iii) the change in pH of the solution will affect the rate of reaction (iv) doubling the concentration of H^(+) ions will increase the reactions rate by 4 items.
