Answer :
-484KJ
Solution :
- The amount of heat liberated when one mile of substance burnt is called enthalpy of combustion
- Given , on combustion of 0.5 mole , liberates -242KJ of heat
- 0.5 mole ------> -242KJ
- 1 mole ----------> x KJ
- Upon cross multiplying ,
- 0.5x = 1×(-242)KJ
- x = -242/0.5 KJ
- x = -484 KJ
Therefore , enthalpy of combustion is -484KJ/mol
