A) \[280\,kJ\,mo{{l}^{-1}}\]
B) \[285\text{ }kJmo{{l}^{-1}}\]
C) \[270\text{ }kJ\,mo{{l}^{-1}}\]
D) \[15\,kJ\,mo{{l}^{-1}}\]
Correct Answer: B
Solution :
[b] \[X\xrightarrow{{}}Y;\Delta H=-135\,kJ/mol,\] \[{{E}_{a}}=150kJ/mol\] For an exothermic reaction \[{{E}_{a(F.R)}}=\Delta H+E{{'}_{a(B.R.)}}\] \[150=-135+E{{'}_{a(B.R.)}}\] \[E{{'}_{a(B.R.)}}=285kJ/mol\]You need to login to perform this action.
