Q. Point out the wrong statement: For a first order reaction
Chemical Kinetics
A
time for half-change $\left(t_{1 / 2}\right)$ is independent of initial concentration
2%
B
change in the concentration unit does not change the rate constant $(k)$
7%
C
time for half-change $\times$ rate constant $=0.693$.
2%
D
the unit of $k$ is $mol ^{-1} \min ^{-1}$
90%
Solution:
Unit of $k$ for $I^\text{st}$ order reaction is (Time) ${ }^{-1}$
