A) \[{{10}^{-1}}\]
B) \[{{10}^{-2}}\]
C) \[2\times {{10}^{-3}}\]
D) \[2\times {{10}^{-2}}\]
Correct Answer: A
Solution :
Arrhenius equation is, rate constant, \[k=A{{e}^{-{{E}_{a}}/RT}}\] \[k=A{{e}^{-2.303\,RT/RT}}\Rightarrow \frac{k}{A}={{e}^{-2.303}}\] on solving, we get \[\frac{k}{A}={{10}^{-1}}\]
