Assertion: According to Arrhenius equation \[K=A{{e}^{-{{E}_{a}}/RT}},\] ne energy of activation is independent of temperature. Reason: The plot of log k versus 1/T is linear

A)  assertion and reason both are correct and reason is the correct explanation of assertion

B)  assertion and reason both are correct but reason is NOT the correct explanation of assertion

C)  assertion is true but reason is false

D)  both assertion and reason are false

Correct Answer: A

Solution :

: \[K=A{{e}^{-{{E}_{a}}/RT}}\] Taking log, \[\log K=\log A-\frac{{{E}_{a}}}{2.303RT}\]
