Q. Rate constant in case of first order reaction is
Chemical Kinetics
A
inversely proportional to the concentration units
15%
B
independent of concentration units
39%
C
directly proportional to the concentration units
36%
D
inversely proportional to the square of the concentration units.
9%
Solution:
For a first order reaction
$k=\frac{2.303}{K}log \frac{[A]_0}{[A]}$
.' .Rate constant, k is independent of concentration unit
