A) 214.8kJ
B) 314.8kJ
C) 414.8kJ
D) 514.8kJ
Correct Answer: B
Solution :
\[\underset{12\,\,g}{\mathop{C+}}\,\,\,\,\,\underset{32\,\,g}{\mathop{{{O}_{2}}}}\,\xrightarrow{{}}\underset{44\,\,g}{\mathop{C{{O}_{2}}}}\,\,;\,{{\Delta }_{c}}H=-393.5\,kJ\,mo{{l}^{-1}}\] \[\because \] Due to \[44\,g\,C{{O}_{2}}\], heat releases = 393.5 kJ \[\therefore \] Due to 35.2 g \[C{{O}_{2}}\], heat releases \[=\frac{393.5\times 35.2}{44}\] = 314.8 kJYou need to login to perform this action.
