A) 2.494
B) 24.94
C) 249.4
D) 2494
Correct Answer: C
Solution :
[c] Given,\[k=5\times {{10}^{11}}{{e}^{-30,000/T}}\] ...(i) Arrhenius equation is as \[k=A{{e}^{-{{E}_{a}}/RT}}\] ...(ii) From Eqs. (i) and (ii) \[-\frac{30000}{T}=-\frac{{{E}_{a}}}{RT}\] \[\therefore \] \[{{E}_{a}}=30,000\times R\] \[=30,000\times 8.314\] \[=249420\text{ }J\,mo{{l}^{-1}}\] \[=249.42\text{ }kJ\text{ }mo{{l}^{-1}}\]You need to login to perform this action.
