Solution :
[a] Energy released = Energy due to formation of two single bonds \[=2\times 331=661\,\,kJmo{{l}^{-1}}\]of propene \[\Delta H\]polymerisation / mol \[=590-662=-72\text{ }kJ\text{ }mo{{l}^{-1}}\] \[\Delta H\]polymerisation/mol \[=-72\times n=-360\] \[n=5\]You need to login to perform this action.
