A) \[-1357.9\,\,kJ\]
B) \[-1275.9\,kJ\]
C) \[-1572.0\,kJ\]
D) \[-1165.5\,kJ\]
Correct Answer: C
Solution :
Heat of formation of a substance is the heat exchanged when one mole of that substance is formed by its constituent elements. \[\because \] Heat evolved when 1 mole \[(44g)\,C{{O}_{2}}\] is formed \[=393\,kJ\] \[\therefore \] Heat evolved when \[0.156\,Kg\,(156g)\] is formed \[=\frac{393\times 156}{44}\] \[\therefore \] \[\Delta H\] for the process \[=1572\,kJ\]\[=-1572.0\,kJ\]
