A) 3RT
B) -3RT
C) -4RT
D) 4RT
Correct Answer: C
Solution :
\[{{C}_{7}}{{H}_{16}}(\ell )+11{{O}_{2}}(g)\xrightarrow[{}]{{}}7C{{O}_{2}}(g)+8{{H}_{2}}O(\ell )\] \[\Delta {{n}_{g}}={{n}_{p}}-{{n}_{r}}=7-11=-4\] \[\because \]\[\Delta H=\Delta U+\Delta {{n}_{g}}RT\] \[\therefore \]\[\Delta H-\Delta U=-4RT\]You need to login to perform this action.
