When \(10 \mathrm{~g}\) of methane is completely burnt in oxygen, the heat evolved is \(560 \mathrm{~kJ}\). What is the heat of combustion (in \(\mathrm{kJ} \mathrm{mol}^{-1}\) ) of methane?
- A -1120
- B -968
- C -896
- D -560
Answer & Solution
Correct Answer
(C) -896
Step-by-step Solution
Detailed explanation
\(\mathrm{CH}_4+2 \mathrm{O}_2 \longrightarrow \mathrm{CO}_2+2 \mathrm{H}_2 \mathrm{O}\) \(10 \mathrm{~g} \Delta H=-560 \mathrm{~kJ}\) \((12+4=16) g=1 \mathrm{~mole}\) The heat of combustion of \(10 \mathrm{~g} \mathrm{CH}_4=-560 \mathrm{~kJ}\) So, the heat of combustion of…
