The specific rate constant of a first order reaction depends on the

A

time

B

concentration of the reactant

C

temperature

D

concentration of the product

Text Solution

Verified by Experts

The correct Answer is:
C
The rrate contant `(k)` is a proportionality constant in the relationship between rate and concentration. For every reaction (irrespective or reaction order), it has a fixed value at any given temperature, but it varties with temperature.

The unit of rate constant for a first order reaction

Which factor affect the specific rate constant of a first order reaction ?

The specific rate constant for a first order reaction is 1 times 10^–3 sec^–1 . If the initial concentration of the reactant is 0.1 mole/lt, the rate of reaction mol l^–1 sec^–1 is:

Statement-2: The reciprocal of time in which 66% of the reactant is conveted to product is equal to the rate constant of first order reaction. Because Stetment-2 : The rate constant for first order reaction depends on initial concentration of reactants.
