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