Chemical Kinetics Question 336
Question: Which of the following expression is correct for first order reaction- $ (CO) $ refers to initial concentration of reactant [DCE 2000]
Options:
A) $ {t_{1/2}}\propto CO $
B) $ {t_{1/2}}\propto C{O^{-1}} $
C) $ {t_{1/2}}\propto C{O^{-2}} $
D) $ {t_{1/2}}\propto CO^{0} $
Show Answer
Answer:
Correct Answer: D
Solution:
$ {t_{1/2}}\propto {{(CO)}^{o}} $ i.e. half life for Ist order is independent of initial concentration.
