A) \[+1412\,kJ\,mo{{l}^{-1}}\]
B) \[-1412\,kJ\,mo{{l}^{-1}}\]
C) \[141.2\,kJ\,mo{{l}^{-1}}\]
D) \[-141.2\,kJ\,mo{{l}^{-1}}\]
Correct Answer: B
Solution :
[b] Desired eqn; \[{{C}_{2}}{{H}_{4}}+3{{O}_{2}}\xrightarrow[{}]{}2C{{O}_{2}}+2{{H}_{2}}O\] \[\Delta H=2(-394)+2(-286)-(52)=-1412\,kJ\]You need to login to perform this action.
