Point out the wrong statement: For a first order reaction

Question

Point out the wrong statement: For a first order reaction (A) time for half-change (t1 / 2) is independent of initial concentration (B) change in the concentration unit does not change the rate constant (k) (C) time for half-change × rate constant =0.693. (D) the unit of k is mol -1 min -1

Unit of k for I textst order reaction is (Time) -1

Q. Point out the wrong statement: For a first order reaction

time for half-change $(t_{1/2})$ is independent of initial concentration

change in the concentration unit does not change the rate constant $(k)$

time for half-change $\times$ rate constant $= 0.693$ .

the unit of $k$ is $m o l^{- 1} min^{- 1}$

Unit of $k$ for $I^{st}$ order reaction is (Time) $^{- 1}$

Q. Point out the wrong statement: For a first order reaction

time for half-change (t1/2​) is independent of initial concentration

change in the concentration unit does not change the rate constant (k)

time for half-change × rate constant =0.693.

the unit of k is mol−1min−1

Unit of k for Ist order reaction is (Time) −1

time for half-change $(t_{1/2})$ is independent of initial concentration

change in the concentration unit does not change the rate constant $(k)$

time for half-change $\times$ rate constant $= 0.693$ .

the unit of $k$ is $m o l^{- 1} min^{- 1}$

Unit of $k$ for $I^{st}$ order reaction is (Time) $^{- 1}$
