The heat of combustion \(\left(\mathrm{kJ} \mathrm{mol}^{-3}\right\}\) is highest for
- A \(\mathrm{H}_2(g)\)
- B \(\mathrm{H}_2(\mathrm{O})\)
- C LPG
- D \(\mathrm{CH}_4(g)\)
Answer & Solution
Correct Answer
(C) LPG
Step-by-step Solution
Detailed explanation
The heat change when one mole of the substance is completely burnt in oxygen is called enthalpy of combustion. LPG (Liquefied Petroleum Gas) is mixture of propane or butane. With increase in number of \(\mathrm{C}\)-atom heat of combustion increases. Thus, option (3) is correct.
