Chemical Kinetics Question 36

Question: The temperature dependence of rate constant $ (k) $ of a chemical reaction is written in terms of Arrhenius equation, $ K=A.{e^{-E*/RT}} $ . Activation energy $ ({E^{*}}) $ of the reaction can be calculated by plotting [CBSE PMT 2003]

Options:

A) $ \log ,k,vs,\frac{1}{\log ,T} $

B) $ k,vs,T $

C) $ k,vs,\frac{1}{\log ,T} $

D) $ \log ,k,vs,\frac{1}{T} $

Show Answer

Answer:

Correct Answer: D

Solution:

$ k=A{e^{-E^{0}/RT}} $

$ \underset{y}{\mathop{\log K}},=\underset{c}{\mathop{\log A}},-\underset{mx}{\mathop{E^{o}}},/RT $
$ \therefore \log K,Vs,\frac{1}{T} $ .
