A) \[10\]
B) \[15\]
C) \[30\]
D) \[60\]
Correct Answer: C
Solution :
[c] The overall rate constant \[k=\frac{{{k}_{1}}{{k}_{3}}}{{{k}_{2}}}\] We know; \[k=A{{e}^{-Ea/RT}}\] \[\therefore \,\,\,\,\,\,\,\,k=\frac{{{k}_{1}}{{k}_{3}}}{{{k}_{2}}}=A{{e}^{-({{E}_{a1}}+{{E}_{a3}}-{{E}_{a2}})/RT}}\] \[=A{{e}^{-(40-30+20)/RT}}=A{{e}^{-30/RT}}\] \[\therefore \,\,\,\,\,\,\,\,\,\,\,{{E}_{a}}=30\,kJ\,mo{{l}^{-1}}\]You need to login to perform this action.
