A) 3260
B) -3267.6
C) 4152.6
D) -452.46
Correct Answer: B
Solution :
\[{{C}_{6}}{{H}_{6}}(\ell )+\frac{15}{2}{{O}_{2}}(g)\xrightarrow{{}}6C{{O}_{2}}(g)+3{{H}_{2}}O(\ell )\] \[\Delta {{n}_{g}}=6-7.5=-1.5\] \[\Delta H=\Delta U+\Delta {{n}_{g}}RT\] \[\Delta H=-3263.9-\frac{1.5\times 8.314\times 298}{1000}=-3267.6\,\,kJ\,\,mo{{l}^{-1}}\]You need to login to perform this action.
