Which of the following statements are correct about half life period?
\( \mathrm{P} \)
(A) It is proportional to initial concentration for a zero
W order reaction.
(B) Average life \( =1.44 \) times half life for a first order reaction.
(C) Time of \( 75 \% \) reaction is thrice of half life period in second order reaction.
(D) \( 99.9 \% \) reaction which is first order, takes place in 100 minutes if the rate constant of the reaction is \( 0.0693 \mathrm{~min}^{-1} \).
