A) 2.494
B) 24.94
C) 249.42
D) 2494
Correct Answer: C
Solution :
Given, \[k=5\times {{10}^{11}}{{e}^{-30,000/T}}\] ?(i) Arrhenius equation is as \[k=A{{e}^{-{{E}_{a}}/RT}}\] From Eqs. (i) and (ii) \[-\frac{30000}{T}=\frac{{{E}_{a}}}{RT}\] \[\therefore \] \[{{E}_{a}}=30,000\times R\] \[=249420\,J\,mo{{l}^{-1}}\] \[=-249.42\,kJ\,mo{{l}^{-}}\]You need to login to perform this action.
