Chemical Kinetics Question 342
Question: The rate constant for a first order reaction whose half life is 480 sec, is:
Options:
A) $ 1.44\times {10^{-3}}se{c^{-1}} $
B) $ 1.44\times se{c^{-1}} $
C) $ 0.72\times {10^{-3}}se{c^{-1}} $
D) $ 2.88\times {10^{-3}}se{c^{-1}} $
Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ k=\frac{0.693}{{t_{1/2}}}=\frac{0.693}{480}=1.44\times {10^{-3}}{s^{-1}} $
