Chemical Kinetics Question 335
Question: The slope in Arrhenius plot, is equal to:
Options:
A) $ -\frac{E_{a}}{2.303R} $
B) $ \frac{E_{a}}{R} $
C) $ -\frac{R}{2.303E_{a}} $
D) None of these
Show Answer
Answer:
Correct Answer: A
Solution:
[a] Arrhenius equation is given by $ k=A{e^{-E_{a}}}^{/RT} $ Taking log on both sides, we get $ \log k=logA-\frac{E_{a}}{2.303RT} $ Arrhenius plot a graph between log k and $ \frac{1}{T} $ whose slope is $ \frac{-E_{a}}{2.303R}. $
